The probability that exactly 8 individuals do not cover their mouth is 0.0037.
<h3>How to calculate the probability?</h3>
It should be noted that the probability will be solved by using the binomial distribution.
From the information, the probability that a randomly selected individual will not cover his or her mouth when sneezing is 0.267.
Therefore, the probability that thee person will not cover their mouth will be:
= 1 - 0.267
= 0.733
This will be:
= 12C8 × (0.267)^8 × (1 - 0.267)⁴
= 12C8 × (0.267)^8 × 0.733⁴
= 495 × 0.00002582 × 0.28867
= 0.0037
In conclusion, the probability is 0.0037.
