Question

A coin is tossed 100 times with following frequency.
Head: 25, Tail: 75.
(i) Find the probability of getting a tail?
(ii) Find the probability of getting a Head?

Answer 1

(i) Frequency of tail =75
Total number of trials =100
P(getting a tail) $=\frac{75}{100}=\frac{3}{4}$
(ii) Frequency of heads =25
Total number of trials =100
P(getting a heads) $=\frac{25}{100}=\frac{1}{4}$
