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

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

step-by-step explanation:

good luck

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
