Approximately 3.4% of Americans are vegetarian. If we ask a random sample of 36 people, what is the probability that exactly 4 of them are vegetarian?

Respuesta :

Answer:

0

Step-by-step explanation:

Given:  3.4% of Americans are vegetarian.

sample size  = 36 people

Therefore, 3.4% of 36 = 1.224.

Hence, out of 36 people only 1.224 people which is approximately 1 is vegetarian.

So, the probability of exactly 4 people being vegetarian out of 36 people would be zero.

As out of 36 only 1 was vegetarian.

Hence, the correct answer would be 0
