Answer to Problem 4CYU
Probability is
Explanation of Solution
Given information :
Total students are 100
Now the probability that the student is junior,
Total junior are 39
Hence the probability that the student is junior from 100 students is
Similarly probability that the student is from debate is
Now the probability the student is junior or student is from debate is,
(Given events are mutually exclusive)
Hence,
P(junior or debate) =
There are 6 students sharing both debate and junior,
P(junior or debate) =
