5. A bag holds 2 yellow, 1 green, and 2 red marbles. If you were to draw a marble from the bag 150 times, and replace it after each draw, how many yellow marbles would you expect to draw?
The first thing to notice is that each time you draw a marble, you have a 2/5 chance of drawing a yellow marble (since there are two yellow marbles out of a total of five marbles). This probability stays the same for each draw, because you replace the marble after drawing it (so the total number of marbles remains constant).
To find the expected number of yellow marbles drawn, you can multiply the probability of drawing a yellow marble by the total number of times the marble is drawn. Let's call the number of yellow marbles drawn "Y". Then:
Expected value of Y = (probability of drawing yellow marble) x (total number of draws)
= (2/5) x (150)
= 60
So you would expect to draw 60 yellow marbles out of the 150 total draws, on average. I hope that helps!
