One ball is selected at random from a bag. This is repeated 400 times. If there are 4 red balls, 3green balls and one blue ball how many times would u expect to select a blue ball

Question

Probability

Answer 1

since we have 8 balls in total and 1 blue ball, the probability to pick one blue ball is 1/8

if we repeat this for 400 times the prbability to pick a blue ball from the bag is 400/8=50 times
