Question

Problem 20E

In a binomial distribution n = 12 and π = .60. Find the following probabilities.

a. x = 5.

b. x ≤ 5.

c. x ≥ 6.

Solution

Solution 20E

Step1 of 4:

From the given problem we have a random variable ‘x’ follows a binomial distribution with parameters ‘n = 12 and ’.

Here our goal is:

a). We need the probabilities of x = 5.

b). We need the probabilities of x ≤ 5.

c). We need the probabilities of x ≥ 6.


Step2 of 4:

a).

We know that ‘x’ follows a binomial distribution with parameters ‘n = 12 and ’. Then, the probability mass function of the binomial distribution is:

Now,
