Chapter 10.6, Problem 9GP

To determine

To find: The probability as a fraction and as a percent.

Answer to Problem 9GP

The probability in fraction is $\frac{9}{10}$ .

The probability in percent is $90\%$ .

Probability of the event is likely to occur.

Explanation of Solution

Given information: The spinner is shown in figure.

Calculation: The spinner is shown in figure.

Total outcomes $=10$ .

Favourable outcomes $=1,2,3,5,6,7,8,9,10$ .

Number of favourable outcomes $=9$ .

  $\begin{array}{l}\mathrm{P}(\mathrm{not}4)=\frac{9}{10}\\ \mathrm{In}\mathrm{percent}=\frac{9}{10}\times 100\%=9\times 10\%=90\%\end{array}$

Probability of event is more than $50\%$ ,So the event is likely to occur.

Thus, the probability in fraction is $\frac{9}{10}$ ,the probability in percent is $90\%$ and Probability of the event is likely to occur.
