Question

One week kit has homework for maths and geography.

The probability of kit doing his maths homework is 0.8.

The probability of kit doing his geography homework is 0.6.

Work out the probability that kit does at least one of his homeworks.

Answer 1

P(M) = .8

P(G) = .6

P(M^G) = .8(.6) = .48

P(MvG) = P(M)+P(G) - P(M^G) = .8+.6 - .48 = 0.92 = 92% chance he'll do at least one of the homeworks

this assumes doing the math homework is independent of the event of doing the geography homework
