Question

For a student the probability of getting admission in IIT is 60% and probability of getting admission in Anna university is 75%. Find the probability that 

(i) getting admission in only one of these,

(ii) getting admission in atleast one of these

Answer 1

Probability of getting admission in IIT = P(A) = 60% = 60/100 = 3/5

Therefore P(A') = 1 - P(A) = 1- 3/5 = 2/5

Probability of getting admission in Anna university = P(B) = 75%

= 75/100 = 3/4

So, P(B') = 1 - 3/4 = 1/4

(i) Probability of getting admission in only one 

(ii) Getting admission in atleast one
