Answer 1

We have to determine the probability that a person who does not go to the movies at least twice a week is male.

From the table , it is given that there are total 73 students who does not go to school atleast twice a week.

Also, the number of male students whod does not go to school atleast twice a week is, 45.

Therefore, the probability that a person who does not go to the movies at least twice a week is male is determined as.

$P=\frac{45}{73}$$P=0.61643$
