Questions & Step-by-Step Solutions
A bag contains 5 red balls and 3 blue balls. If one ball is drawn at random, what is the probability that it is blue?
Step 1: Count the total number of balls in the bag. There are 5 red balls and 3 blue balls.
Step 2: Add the number of red balls and blue balls together. So, 5 + 3 = 8 total balls.
Step 3: Count how many of the balls are blue. There are 3 blue balls.
Step 4: To find the probability of drawing a blue ball, divide the number of blue balls by the total number of balls. So, 3 (blue balls) divided by 8 (total balls) equals 3/8.
Step 5: The probability of drawing a blue ball is 3/8.
