(Round your answer to two decimal places.) If the group of 11 teenagers in the tent is a random sample, then there is a % chance that 2 or more teenagers will be afraid of spiders in any particular tent.

Answer:

YES, there are 88% chances that no more than one of them is afraid of spider.

If there is group of 11 teenager in tent, then there is chance that 2 0r more teenager will be afraid of spider.

Step-by-step explanation:

Let A11 be the number of teenager. We want no more than one teenager in each tent is afraid of spider

P (C11≤1) = P (C11=0) + P (C11=1)

               = (11C0) 0.070. (1- 0.07)10 + (11C1). 0.071. (1- 0.07)10-1

               = 0.88

               = 88 %

Yes, it seems reasonable for him to randomly assign teenagers to tents.

There are 88% chances that no more than one of them is afraid of a spider, remaining are in his favor, and he can randomly assign.

If there is a group of 11 teenagers intent, then there is a chance that two 0r more teenagers will be afraid of a spider.

Probability = P (C11≤2)

                  = P(C11 = 2) + P  (C11=3) + P(C11 =4) + ……

          (Probability is somewhat large)
