Question

A fair coin is tossed $60$ times and it came up with tails $27$ times. Find the probability of head.

Answer 1

Find the probability of head.

Total number of times coin tossed $=60$

Number of times tail appears $=27$

Number of times head appears $=60-27=33$

The probability of an event $A$ is given by:

$P\left(A\right)=\frac{Numberoffavourableoutcomes}{Totalnumberofoutcomes}$

Probability of head $=\frac{Numberoftimesheadappears}{Totalnumberoftimesacoinistossed}$

$$\begin{gathered} =\frac{33}{60} \\ =\frac{11}{20} \end{gathered}$$

Hence, the probability of a head is $\frac{11}{20}$
