Question

a bag with 8 marbles has 2 red marbles, 3 yellow marbles, and 3 blue marbles. a marble is chosen from the bag at random. what is the probability that it is red? write your answer as a fraction in simplest form.

Explanation:

Step1: Identify total and favorable outcomes

Total marbles = 8, red marbles = 2

Step2: Apply probability formula

Probability = $\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}=\frac{2}{8}$

Step3: Simplify the fraction

$\frac{2\div2}{8\div2}=\frac{1}{4}$

Answer:

$\frac{1}{4}$
