Question

two coins are tossed simultaneous 1000 times with the following frequencies of different outcomes (1)
(1) two head = 210 times
(2) one heads 550 times
(3)no head =240
find the probability of occurrence of each of these events

Answer 1

1. P = 210 / 1000 = 21 / 100
2. P = 550 / 1000 = 11 / 20
3. P = 240 / 1000 = 6 / 25
