Answer:
[tex]\textbf{The probability that B is not selected = }\bf\frac{5}{6}[/tex]
Step-by-step explanation:
A chairman is to be randomly selected from six people: A, B, C, D, E, and F
So, Total number of peoples available to be selected for chairman = 6
[tex]\text{Probability that B is selected = }\frac{1}{6}[/tex]
Now, we need to find the probability that B is not selected
So, The probability that B is not selected = 1 - Probability that B is selected
[tex]\text{So, The probability that B is not selected = }1-\frac{1}{6}=\frac{5}{6}[/tex]
[tex]\textbf{Hence, The probability that B is not selected = }\bf\frac{5}{6}[/tex]
