Mr. Lim has a bag with some marbles colored red, yellow, green, blue, and white. The marbles are identical in number. Mr. Lim will conduct a chance experiment by randomly drawing a marble from the bag and then returning it after noting the color. Based on 50 trials, how many green marbles will Mr. Lim expect to pick?(1 point) green marbles

1 answer

Based on the information given, Mr. Lim has marbles of five different colors in the bag, and they are identical in number. Since there are a total of 5 colors and they are equally likely to be picked during each trial, the probability of picking a green marble in one trial is 1/5 or 0.2.

In 50 trials, we would expect Mr. Lim to pick a green marble approximately 0.2 * 50 = 10 times. Therefore, Mr. Lim can expect to pick about 10 green marbles in 50 trials.
