Chapter SH, Problem 13.6.4EP

To determine

To find:the probability of getting yellow.

Answer to Problem 13.6.4EP

The required probability is $\frac{2}{15}$ or $13.3\%$

Explanation of Solution

Given:

Number of blue marbles is 4

Number of red marbles is 6

Number of green marbles is 3

Number of yellow marbles is 2

Select one marble at random.

Calculation:

Total number of marbles is $4+6+3+2=15$

Number of green marbles is 2

  $\begin{array}{l}P(yellow)=\frac{\text{ number of yellow marbles }}{\text{ total number of marbles }}\\ =\frac{2}{15}\\ =\frac{2}{15}\\ =13.3\%\end{array}$

Hence, the required probability is $\frac{2}{15}$ or $13.3\%$

Conclusion:

Therefore, the required probability is $\frac{2}{15}$ or $13.3\%$
