?

What is the probability?

2.Identify the sample space of the probability experiment and determine the number of outcomes in the sample space.

-Randomly choosing an even number between 10 and 20, inclusive

The sample space is?

(Use a comma to separate answers)

There are _____ outcomes in the sample space

3. Determine the number of outcomes in the event. Decide whether the event is a simple event or not.

-You randomly select one card from a standard deck of 52 playing cards. Event

Upper B is selecting a queen.

Event B has ___ outcomes

4. A realtor uses a lock box to store the keys to a house that is for sale. The access code for the lock box consists of six digits. The first digit cannot be zero and the last digit must be odd. How many different codes are? available?

What is he number of different codes available?

5. Use the frequency? distribution, which shows the number of American voters? (in millions) according to? age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range

Ages

Frequency

18 to 20

5.8

21 to 24

7.8

25 to 34

21.8

35 to 44

24.7

45 to 64

52.2

65 and over

27.9

The probability that a voter chosen at random is in the 18 to 20 years old age range is?

Homework Answers

Answer #1

1)probability of selecting the number 595 =1/500

2)the sample space is x: 10<=x<=20 or x:{ 10,11,12,13,14,15,16,17,18,19,20}

There are _11_ outcomes in the sample space

3)

Event B has 4 outcomes

4)

for first digit 9 choices are there ;for middle 4 digits each has 10 choices and for last digit 5 choices

hence total codes=9*10*10*10*10*5=450000

5)

probability that a voter chosen at random is in the 18 to 20 years old age range is

=5.8/(5.8+7.8+21.8+24.7+52.2+27.9)=0.0414
