Question

If there are two events thay can happen in m and n ways then probability of happening of either is

Answer 1

Step-by-step explanation:

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) = 6/81 = 2/27.

Answer 2

Probability of m occuring = m / m+ n

Probability of n occuring = n / m +n

Total probability aka either occuring = m + n / m +n = 1.
