Question

On school swimming day Roger swims in the 50m, 100m and 200m
Freestyle races. Roger estimates that he has equal chances of
winning or losing each race. What is the probability that he wins at
least two races?

Answer 1

Just multiply the probability of the first event by the second for example if the probability of event a is 2/9 and the probability of event b is 3/9 then the probability of both events happening at the same time is 2/9*3/9

therefore 6/8 is equal to 2/27

I have given u an example, take it as a sample

hope u will try...
