प्रश्न
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 head
उत्तर
∵ Total number of possible outcomes = 80
and, the number of favourable outcomes of getting head = 38
∴ Probability of getting a head =`"Number of favourable outcomes"/"Total number of outcomes"`
= `38/80=19/40`
