Solve the following problems below. Show your complete solutions. 1. A bag contains 5 red marbles, 3 blue marbles, and 2 green marbles. What is the probability of drawing a red marble or a blue marble?

To find the probability of drawing a red marble or a blue marble, we first need to determine the total number of marbles in the bag. Total marbles = 5 (red) + 3 (blue) + 2 (green) = 10 marbles. Next, we calculate the number of favorable outcomes for drawing a red or a blue marble: Favorable outcomes = 5 (red) + 3 (blue) = 8 favorable outcomes. Now, we apply the probability formula: Probability of drawing a red or blue marble = (Favorable outcomes) / (Total outcomes) = 8 / 10 = 4 / 5. So, the probability of drawing a red marble or a blue marble is **4/5**.
