Question

At the summer camp, with 8 teenagers in each tent, what is the probability that at most 6 of them suffer from arachnophobia?

a) 0.93
b) 0.07
c) 0.9961
d) 0.0039

Answer 1

The probability cannot be determined from the given information.

Step-by-step explanation:

To find the probability that at most 6 teenagers in a tent suffer from arachnophobia, we need to determine the probability of each possible outcome and then add them together. We can use the binomial probability formula, which is given by:

P(x ≤ k) = C(n, x) * p^x * (1-p)^(n-x)

Where x is the number of teenagers suffering from arachnophobia, n is the total number of teenagers in the tent, C(n, x) is the number of combinations of n objects taken x at a time, and p is the probability that a teenager suffers from arachnophobia.

In this case, n = 8, x can be 0, 1, 2, 3, 4, 5, or 6, and p is not given. Without the probability of a teenager suffering from arachnophobia, we cannot calculate the exact probability. Therefore, the correct answer cannot be determined from the given information.
