Since there are an equal number of marbles of each color in the bag, the probability of picking a green marble in one trial is 1/5.
Therefore, in 50 trials, Mr. Lim can expect to pick green marbles approximately (1/5) * 50 = 10 times.
So, Mr. Lim can expect to pick 10 green marbles in 50 trials.
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?
