Question

if a single choice is made from the group of marbles shown, find the probability of the event that a green marble is chosen. b = blue g = green r = red y = yellow the probability is . (type a whole number or a simplified fraction.)

Explanation:

Step1: Count total marbles

There are 8 marbles in total.

Step2: Count green marbles

There are 2 green marbles.

Step3: Calculate probability

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(\text{green})=\frac{2}{8}$.

Step4: Simplify fraction

$\frac{2}{8}=\frac{1}{4}$.

Answer:

$\frac{1}{4}$
