A coin is tossed 80 times and the head is obtained 38 times. Now, if a coin tossed once, what will the probability of getting a tail
Advertisements
उत्तर
∵ Total number of possible outcomes = 80
and, the number of favourable outcomes of getting a tail = 80 − 38 = 42
∴ Probability of getting a tail =`"Number of favourable outcomes"/"Total number of outcomes"`
= `42/80=21/40`
