Question

Q1.

Part a) A bag contains 12 marbles. There are 4 marbles that are pink, 5 are purple, and 3 are blue. A marble is randomly pulled out of the bag. What is the probability that the marble selected is pink or blue? Round to 4 decimals.

Part b) A student randomly guesses on a 20 question true/false test. What is the probability that the student guesses correctly on 15 of the questions? Round to 4 decimals.

Part c) A student advisory committee is being formed. There will be 6 people chosen from a group of 18 boys and 15 girls. What is the probability that the committee will include at least 4 boys? Round to 4 decimals.

Part d) A party planner is selecting the menu for the party and there will be six total entrees served. There are 4 beef options, 5 chicken options, and 3 vegetarian options to choose from. What is the probability that exactly 3 of the 6 entrees served are chicken?

Q2.

You went on spring vacation and missed school so you need to make up your homework. You are missing 4 math assignments and 2 science assignments and 3 social studies assignments. What is the probability that the assignments from each class will be completed together (i.e. all of one class, then all of another class, then all of another class)? Round to 4 decimals.

Please answer all parts really need the help. I will rate immediately after answering thank you!

Answer #1

Suppose you have a bag with the following marbles: four (4) red,
six (6) pink, two (2) green, and seven (7) blue. Write any
probability as a decimal to three place values and the odds using a
colon. Determine the following:
a. The odds against pulling out a pink marble is
b.. The probability for pulling out a green or blue marble
is
c. The odds of pulling out either a green or red marble is

A bag contains 4 red marbles, 3 green ones, 2 white marbles, and
2 pink marbles. HINT [See Example 7.] You randomly grab 8 marbles.
What is the probability that this set will contain all the red
marbles?

Suppose there is a bag containing 15 pink marbles (Upper P),
15 green marbles (Upper G), 15 violet marbles (Upper V), and 15
black marbles (Upper B). Someone mixes the marbles thoroughly,
draws one marble at random, puts the marble back in the bag,
mixes the bag thoroughly, and draws another marble at random.
Complete parts (a) and (b) below.
List all possible outcomes of this process. Choose the correct
answer below.
. Make the probability distribution showing the probability...

1. A bag contains one green marble, two yellow marbles, four
blue marbles, and five red marbles.
a. What is the theoretical probability of randomly drawing a
blue marble from the bag?
b. If you triple the number of green, yellow, blue, and red
marbles in the bag, what will be the theoretical probability of
drawing a blue marble?
C. Compare your answers for part (a) and (b). Are they the same
or different? Explain.
d. How many blue marbles...

A bag contains 8 blue marbles, 3 red marbles, 7 yellow marbles.
If one marble is drawn from the bag then replaced, what is the
probability of drawing a blue marble then a yellow marble?
In a number guessing game. You ask a person to guess a number
from one 1 to 10. If the person makes a random guess, what is the
probability their guess will be less than 3?
A bag contains 3 white marbles, 7 yellow marbles,...

1. A bag contains 10 black marbles, 8 red marbles, 7
yellow marbles. If one marble is drawn from the bag then replaced,
what is the probability of drawing a black marble then a yellow
marble?
2. In a number guess game you ask a person to guess a
number from 1 to 10. If the person makes a random guess, what is
the probability their guess will be less than 4?
3. A bag contains 8 blue marbles, 7...

A bag contains 3 red marbles, 5 blue marbles, 8 yellow marbles,
and 7 green marbles. What is the probability of choosing a yellow
or green marble when one marble is drawn?

A bag contains 3 red marbles, 5 blue marbles, 8 yellow marbles,
and 7 green marbles. What is the probability of choosing a yellow
or green marble when one marble is drawn?

A bag contains 6 red, 5 white, and 8 blue marbles. Find the
probability of picking 3 white marbles if each marble is NOT
returned to the bag before the next marble is picked. Include
several decimal places, or round to the nearest fourth decimal
place.

1.A bag contains 5blue, 4 red, and 3green marbles. Four
marbles are drawn at random from the bag. How many different
samples are possible which include exactly two red marbles?
2.A bag contains 5 blue, 3 red, and 4 green marbles. Four
marbles are drawn at random from the bag. How many different
samples are possible which include at least one marble of each
color
