0.0645 = 6.45% probability that exactly 10 employees will be tested in order to find 3 positives
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
40% of the employees have positive indications of asbestos in their lungs

a) Find the probability that exactly 10 employees will be tested in order to find 3 positives
2 within the first 9(
when
), and the 10th, with 0.4 probability. So


0.4*0.1612 = 0.0645
0.0645 = 6.45% probability that exactly 10 employees will be tested in order to find 3 positives
