Answer:

Addition used for 'either or' events , Multiplication used for 'and' events

Explanation:

Addition is used when Probability is of 'one event <u>or</u> other event'

Multiplication is used when Probability is of 'one event & other event'

Ex : Probability of A winning = 0.4

Probability of B winning = 0.3

Probability (A or B winning) = 0.4 + 0.3 = 0.7

Probability (A & B winning) = 0.4 x 0.3 = 0.12
