Chapter 0, Problem 65PR

To determine

The probability of finding head on the coin after tossing 50 times.

Answer to Problem 65PR

  $P=\frac{11}{25}$

Explanation of Solution

Given:

Total number of tossing = 50 times

Head appear on top after tossing = 22 times

Formula used:

Probability (P) = $\frac{\text{Possible event}\left(PE\right)}{\text{Total event}\left(TE\right)}$

Calculation:

Total event = total number of tossing

  $TE=50$

Possible event = head appear on top after tossing

  $PE=22$

By the probability formula,

  $\begin{array}{l}P=\frac{PE}{TE}\\ P=\frac{22}{50}\\ P=\frac{11}{25}\end{array}$

Conclusion:

Hence, the probability of finding head on the coin after tossing 50 times is $\frac{11}{25}$ .
