(b) 0.4
(c) 0.45
(d) 0.6

Solution:

Given 3 out of 5 students can participate in a competition

Probability of participation is 3/5

We know that total probability is 1

Probability of non participation is 1 - 3/5 = 2/5

✦ Try This: In a school only, 2 out of 7 students can participate in a competition. What is the probability of the students who do not make it to the competition? (a) 0.65, (b) 0.4, (c) 0.45, (d) 0.6

Given 2 out of 7 students can participate in a competition

Probability of participation is 2/7

We know that total probability is 1

Probability of non participation is 1 - 2/7 = 5/7
