There is an equal amount of yellow, blue, green, and red marbles in a bag of 32 marbles. If Ed draws 4 marbles out of the bag with replacement, predict how many of the 4 marbles drawn should be blue.
1
4
8
32
The probability of drawing a blue marble from the bag is 1/4 since there are 8 blue marbles out of 32 total marbles. This probability remains the same for each draw since Ed is replacing the marbles after each draw.
Therefore, we can expect Ed to draw approximately 1 blue marble out of the 4 marbles drawn with replacement.
So the answer is: 1
