13. Suppose you had to guess on a four-choice multiple-choice test and were given four questions . Find the binomial probability distribution. (p + q)^n when n = 4 and p = 0.25

Respuesta :

Answer:

Binomial probability distribution = 1

Step-by-step explanation:

According to the question:

the binomial probability distribution = (p + q) ^n

Probability of success, p = 0.25

p + q =  1

Probability of failure, q = 1 - p

q = 1 - 0.25 = 0.75

number of guesses, n = 4

Binomial probability distribution = (0.75 + 0.25) ^ 4

Binomial probability distribution = 1^4

Binomial probability distribution = 1
