Two coins are tossed simultaneous 500 times with the following frequencies of different outcomes.
Two tails = 110 times
One tail = 200 times
No tail = 190 times
Find the probability of occurrence of each events.

Text Solution

Verified by Experts

Let `E_(1)` = getting two tails = 110, `E_(2)` = getting one tail = 200, `E_(3)` = getting no tail = 190.
Total number of trials (n) = 500
`P(E_(1))=(E_(1))/(n)=(110)/(500)=(11)/(50)`
`P(E_(2))=(E_(2))/(n)=(200)/(500)=(2)/(5)`
`P(E_(3))=(E_(3))/(n)=(190)/(500)=(19)/(50)`
