Then, answer Part B. A number cube that has sides numbered 1 through 6 is rolled 180 times. Part A How many times would you expe
Nitella [24]

Using the binomial distribution, it is found that the expected values are given by:

a) 120.

b) 150.

<h3>What is the binomial probability distribution?</h3>

It is the probability of <u>exactly x successes on n repeated trials, with p probability</u> of a success on each trial.

The expected value of the binomial distribution is:

E(X) = np

In this problem, for both items, we consider that the number cube is rolled 180 times, hence n = 180.

Item a:

4 of the 6 possible values are greater than 2, hence p = 4/6 = 2/3.

The expected value is given by:
E(X) = 180 x 2/3 = 120.

Item b:

5 of the 6 values are less than 6, hence p = 5/6.

The expected value is given by:
E(X) = 180 x 5/6 = 150.

What is the probality of rolling a sum of 5 if two regular 6 -sides number cubes are rolled
Dmitry [639]

Each die has six numbers, the total number of possible combinations is 6 * 6 = 36


The combinations in which you can get a sum of 5 are:  1 &4, 2 & 3, 4 &1, 3 &2

There are 4 different combinations of getting a sum of 5.


The probability would be 4/36, which reduces to 1/9
