Two coins are tossed simultaneous 1000 times with the following frequencies of different outcomes: Two heads:  210 times One head:    550 times No head :     240 times Find the probability of occurrence of each of these events.

Text Solution

Verified by Experts

Total outcomes`=1000`
Let `E_1="event of getting two heads", E_2="Getting one head" and E_3="getting no head"`
(1)P(E_1)`=210/1000=0.21`
(2)P(E_2)`=550/1000=0.55`
(3)P(E_3)`=240/1000=0.24`
