guns 'n' roses

Recommended Posts

hi I have this practice question and needed help with the answers:

Alan has 2 squash partners, Steve and Connor.

If he plays steve he has 30% of a chance of winning.

If he plays connor he has 50% of a chance of winning.

He plays steve 20% of the time and connor the rest.

what's the probability of Alan winning a match?

given that Alan doesn't win, what is the probability that he was playing Connor?

answers to 3 d.p.

Thanks
