Question

odds in favour of one student passing test 3:7.the odds against another student passing 3:5 both fail is

Answer 1

Step-by-step explanation:

Probability of first student passing is 3/10

Probability of second student passing is 5/8

as both events can happen together, these are independent events.

so, probability of both failing is

P(A') × P(B') = 7/10 ×3/8

=21/ 80
