Question

a bag with 8 marbles has 4 red marbles, 3 yellow marbles, and 1 blue marble. 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 = 4

Step2: Calculate probability

Probability = $\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}=\frac{4}{8}$

Step3: Simplify the fraction

$\frac{4\div4}{8\div4}=\frac{1}{2}$

Answer:

$\frac{1}{2}$
