Upon flipping a coin three consecutive times, use a tree diagram to determine the event that includes all of the outcomes where, at most, two tails are flipped.
In how many ways can 2 coins be chosen from a set of 2 pennies, 2 nickels, 2 dimes, and 1 quarter? Make an organized list to show the sample space. Use P for penny, N for nickel, D for dime, and Q for quarter.
In how many ways can a shirt and a hat be chosen, given 20 shirts and 13 hats to choose from?
If two spinners are spun, where the first is numbered from 1 to 2 and the second from 1 to 9, determine the probability of both spinners stopping at even numbers using a tree diagram.
Suppose there are 9 sheep whose fur may be only one of two colors, white or brown. Using the tree diagram, determine the total number of possible sheep-color choices.
