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)
the answer is 8 because 40 divided by 5 = 8
Since the marbles are identical in number, the probability of picking a green marble in each trial is 1/5.
Therefore, in 50 trials, Mr. Lim can expect to pick (1/5) * 50 = 10 green marbles.
So, Mr. Lim will expect to pick 10 green marbles in 50 trials.
