Correct answer only !

in which distributions does the variable x have a binomial distribution?

select each correct answer.

b) rolled three times, number of 2s rolled

              d) rolled twice, number of odds rolled

Step-by-step explanation:

A binomial experiment must meet the following criteria:

a) rolled twice --> satisfies #1 & #2 (n = 2)

   X is the sum --> fails #3 (more than two outcomes)

b) rolled three times --> satisfies #1 & #2 (n = 3)

   X is the number of 2s rolled --> satisfies #3 & #4 (P success = 1/6)

c) rolled an unknown number of times - fails #1

d) rolled twice --> satisfies #1 & #2 (n = 2)

   X is the number of odds rolled --> satisfies #3 & #4 (P success = 1/2)

the answer is 11.2 (i know i’m late)
