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) help
Based on the information provided, the probability of picking a green marble in each trial is 1/5 since there are 5 different colors in total.
To find the expected number of green marbles in 50 trials, we multiply the probability of picking a green marble in each individual trial (1/5) by the total number of trials (50):
Expected number of green marbles = (1/5) * 50 = 10
Therefore, Mr. Lim can expect to pick around 10 green marbles in 50 trials.
