Vedclass · Answer

(B) The probability of an event is given by the ratio of the number of favorable outcomes to the total number of possible outcomes.Here, the total number of employees (total outcomes) = $100$.The frequency of the unit digit $3$ (favorable outcomes) = $15$.Therefore, the probability that a randomly selected employee has a telephone number with unit digit $3$ is:$P(	ext{unit digit } 3) = \frac{	ext{Frequency of } 3}{	ext{Total number of employees}}$$P(	ext{unit digit } 3) = \frac{15}{100} = 0.15$.

Unit digit	$0$	$1$	$2$	$3$	$4$	$5$	$6$	$7$	$8$	$9$
Frequency	$8$	$9$	$12$	$15$	$10$	$7$	$12$	$10$	$9$	$8$

Outcome	$1$	$2$	$3$	$4$	$5$	$6$
Frequency	$180$	$150$	$160$	$170$	$150$	$190$
