Question

Problem 19E

In a binomial distribution n = 8 and π = .30. Find the probabilities of the following events.

a. x = 2.

b. x ≤ 2 (the probability that x is equal to or less than 2).

c. x ≥ 3 (the probability that x is equal to or greater than 3).

Solution

Solution 19E

Step1 of 4:

From the given problem we have a random variable ‘x’ follows a binomial distribution with parameters ‘n = 8 and ’.

Here our goal is:

a). We need the probabilities of x = 2.

b). We need the probabilities of x ≤ 2.

c). We need the probabilities of x ≥ 3.


Step2 of 4:

a).

We know that ‘x’ follows a binomial distribution with parameters ‘n = 8 and ’. Then, the probability mass function of the binomial distribution is:
