Total number of times that the 2 coins are tossed = 625Total number of possible outcomes = 6251
 Number of times 1 tail appears = 180Number of times 2 tail appears = 220Number of times at leats 1 tail appears = 180 + 220 = 400Number of favourable outcomes = 400Required probability = Number of favourable outcomes Total number of possible outcomes = 400625 = 16252
 Number of times 2 heads appears = 225Number of favourable outcomes = 225Required probability = Number of favourable outcomes Total number of possible outcomes = 225625 = 9253
Number of times 1 tail and 1 head appears = 180Number of favourable outcomes = 180Required probability = Number of favourable outcomes Total number of possible outcomes = 180625 = 36125
