Answer 4

The events 'choosing a senior' and 'choosing a junior' are mutually exclusive (you cannot do both at the same time). Therefore if we find each probability and add the two values we will find the solution.
What is the probability of choosing a senior? You can find it by dividing the number of seniors by the total number in the club. Can you do that and post the result?

Answer 5
