Question

A pair
of dice is rolled 20 times. What is the probability that a sum of 5
is rolled

a)
exactly 6 times

b) at
least 4 times

Answer #1

If
a pair of dice is rolled, what is the probability of a) rolling a
sum of 8, b) rolling a sum of 3 or rolling a sum of 6, c) rolling a
sum of 4 or rolling doubles, if a pair of dice is rolled twice,
whatnis the probability of d) rolling a sum of 9 on the first roll
and rolling a sum of 2 on the second roll

1.) Suppose a pair of dice are rolled. Consider the sum of the
numbers on the top of the dice and find the probabilities. (Enter
the probabilities as fractions.)
(a) 5, given that the sum is odd
(b) odd, given that a 5 was rolled
2.) Suppose a pair of dice are rolled. Consider the sum of the
numbers on the top of the dice and find the probabilities. (Enter
the probabilities as fractions.)
(a) 8, given that exactly one...

A pair of dice are rolled 1,000 times with the following
frequencies of outcomes:
Sum
2
3
4
5
6
7
8
9
10
11
12
Frequency
10
30
50
70
110
150
170
140
120
80
70
Use these frequencies to calculate the approximate empirical
probabilities and odds for the events a. The sum is less than 5 or
greater than 9. b. The sum is even or exactly divisible by 5.

Find the indicated probability.
When a pair of dice are rolled there are 36 different possible
outcomes: 1-1, 1-2, ... 6-6. If a pair of dice are rolled 3 times,
what is the probability of getting a sum of 5 every time? Round to
eight decimal places.

You roll a pair of fair dice 20 times. Each time, the sum of the
two dice values is recorded. What is the probability that you will
roll an 7 (the sum of the two dice values = 7) at least (5) times?
Assuming that each roll of the dice is independent

A pair of dice is rolled 240 times. Use the normal approximation
to binomial distribution the probability that a total of 7
occurs
(a) at least 35 times?
(b) between 36 and 44 times inclusive?
(c) exactly 40 times?

A pair of dice is rolled once. find the probability of obtaining
a sum of 10 or doubles (same number on both dice).

Find the probability that the sum is as stated when a pair of
dice is rolled. (Enter your answers as fractions.) (a) 8 or 11 (b)
8 or 11 or doubles

6. A pair of 10-sided, numbered 1 through 10, dice are rolled.
What is the probability that the sum of the two dice is:
a) 18
b) 19, given that a sum of 18 or more was rolled.

If a pair of dice, one green and one red, is rolled, what is the
probability that the following will occur? (Assume both dice are
six-sided. Enter your probabilities as fractions.)
(a) Pr(3 ≤ S ≤ 4), where S is the sum rolled
(b) Pr(8 ≤ S ≤ 11), where S is the sum rolled
