Question

According to a recent survey 35% of high school students play a sport. If 2 students are randomly chosen from a group of 100 high school students, what is the probability that at least one of them does not play a sport? A 12.25%B 65%C 70%D 88%

Answer 1

ThereforeSince 35% of the student plays a sport

Since there are 100 students in the group

Therefor there are 35 students in this group play sport

$\frac{35}{100}\times100=35$

In at least we will subtract who can play from 100%

So let us find the probability that 1 of the 2 students not play

$undefined$
