Question

A bag contains some red, green, and blue colored marbles. If there are 15 red marbles, 10 blue marbles, and 25 green marbles in the bag, find the probability of getting a green marble from the bag.

• A. $\frac{1}{4}$
• B. $\frac{1}{6}$
• C. $\frac{1}{2}$
• D. $\frac{1}{3}$

Answer 1

The correct option is C $\frac{1}{2}$

Number of red marbles = 15

Number of blue marbles = 10

Number of green marbles = 25

∴ Total number of marbles will be
= 15 + 10 + 25 = 50

$\text{Probability}=\frac{Numberoffavorableoutcomes}{Totalnumberofoutcomes}$

So,
$\text{Probability of getting green marble}=\frac{25}{50}=\frac{1}{2}$

Hence, the probability of getting a $\text{green marble from the bag is}\frac{1}{2}.$
