a bag with 6 marbles has 1 blue marble, 2 yellow marbles, and 3 red marbles. a marble is chosen from the bag at random. what is the probability that it is blue or yellow? write your answer as a fraction in simplest form.
Answer
Answer:
$\frac{1}{2}$
Explanation:
Step1: Calculate favorable outcomes
$1 + 2=3$ (1 blue + 2 yellow)
Step2: Calculate total outcomes
Total marbles = 6
Step3: Calculate probability
Probability = $\frac{\text{Favorable outcomes}}{\text{Total outcomes}}=\frac{3}{6}=\frac{1}{2}$
