Question

a coin is tossed 200 times the head appears 79 times find the probability of getting a tail

Answer 1

$$\begin{gathered} \mathrm{Total}\mathrm{number}\mathrm{of}\mathrm{times}\mathrm{a}\mathrm{coin}\mathrm{is}\mathrm{tossed}=200 \\ \mathrm{Total}\mathrm{number}\mathrm{of}\mathrm{possible}\mathrm{outcomes}=200 \\ \mathrm{Number}\mathrm{of}\mathrm{times}\mathrm{head}\mathrm{appears}=79 \\ \mathrm{So},\mathrm{number}\mathrm{of}\mathrm{times}\mathrm{tail}\mathrm{appears}=200-79=121 \\ \mathrm{number}\mathrm{of}\mathrm{favourable}\mathrm{outcomes}=121 \\ \mathrm{Probability}\mathrm{of}\mathrm{getting}\mathrm{a}\mathrm{tail}=\frac{\mathrm{number}\mathrm{of}\mathrm{favourable}\mathrm{outcomes}}{\mathrm{total}\mathrm{number}\mathrm{of}\mathrm{possible}\mathrm{outcomes}}=\frac{121}{200} \end{gathered}$$
