Question

Two coin is tossed 500 times and we get two head =105 time one head -275 no head =120 time find probability of occurrence of each of these event

Answer 1

Probability is P(E)=total number of event /total number of tossed. Two head is P(E)=105/500=21/100. One head is P(E)=275/500=11/20. No head is P(E)=120/500=6/25
