Chapter SH, Problem 13.6.3EP

To determine

To find:the probability of getting red.

Answer to Problem 13.6.3EP

The required probability is $\frac{2}{5}$ or $40\%$

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 6

  $\begin{array}{l}P(red)=\frac{\text{ number of red marbles }}{\text{ total number of marbles }}\\ =\frac{6}{15}\\ =\frac{2}{5}\\ =40\%\end{array}$

Hence, the required probability is $\frac{2}{5}$ or $40\%$

Conclusion:

Therefore, the required probability is $\frac{2}{5}$ or $40\%$
