A coin is tossed 1200 times whereby head occurred in 745 cases and in the reamaining tail occurred. Find the probability of each event.

Verified by Experts

Given that the coin is tossed 1200 times.
Total number of trials =1200
Let the event of getting a head be H, and getting a tail be T.
The numbre of times the event H occurred =745
Probability of event H, i.e., `P(H)=("Number of times head occurred")/("Total number of trials")=(745)/(1200)=(149)/(240)`
Number of times tail i.e., event T occurred =1200-745=455.
`:.` Probability of event T, i.e., `P(T)=("number of times head occurred")/("total number of trials")`
`=(455)/(1200)=(91)/(240)`
