For mutually exclusive events , probability is calculated by rule of addition PPP. For independent events, joint probability is calculated by rule of multiplication PPxP. Given, probability of having a baby with bih weight 3000 grams; P 0.5 probability of having a baby with bih weight 2500-2999 grams; P 0.2 As these two events are mutually exclusive, probability of having a baby with Bw 2.5 kg; P is calculated by Rule of addition 0.50.2 0.7
