Problem 42E
Suppose x is a binomial random variable with n = 3 and p = .3.
a. Calculate the value of p(x), x = 0, 1, 2, 3, using the formula for a binomial probability distribution.
b. Using your answers to part a, give the probability distribution for x in tabular form.
ANSWER:
Solution 42E
Step1 of 3:
Let us consider a random variable ‘X’ it follows binomial distribution with parameters n = 3, and p = 0.3.
Here our goal is:
a). We need to calculate the value of p(x), x = 0, 1, 2, 3, using the formula for a binomial probability distribution.
b). We need to give the probability distribution for x in tabular form by using your answers to part (a).
Step2 of 3:
a).
Here random variable ‘X’ it follows binomial distribution.
That is,
X B(n, p)
X B(3, 0.3)
We know that the probability mass function of binomial distribution is:
x = 0,1,2,...,n.
Now,
