The probability that 17 adults in a sample of 100 adults pass the fitness test is 0.  0106. option B

What is probability?

Probability can be described as:

  • The ratio of the number of outcomes in an exhaustive set of equally likely outcomes that will produce a given event to the total number of possible outcomes
  • The chance that a particular event will occur

Let's  use the binomial formula to solve this problem.

[tex]P(X) = \frac{n!}{x!(n - x) !} * p^x( 1- p) ^n^-^x[/tex]

Where:

  • p is the probability of success = 0. 10
  • n is the sample size = 100
  • x is the number of successes expected = 17

Now, let's find the probability:

[tex]P(17) = \frac{100!}{17!( 100 - 17)!} * 0. 1 ( 1- 0.1 ) ^1^0^0 ^- ^1^7[/tex]

P = 0. 0106

Hence, the probability that 17 adults in a sample of 100 adults pass the fitness test is 0.  0106. option B
