Leap year has 52 weeks + 1 day If the first week of year start with Monday then the year will end on Monday, hence, there will be 52 Tuesdays and 53 Mondays
(1/3 *1/3)
--------------------------------- = 1/5
{(1/3 * 1/3) + (2/3 * 2/3)}
Prob of A not losing = Prob of A win + Prob of dead heat
similarly for B. So 4/5 + 2/5 = 1 + prob of dead heat. As P(A win) + P(B win) + P(DH) = 1.
Divisible by 30. Not possible.
