If 40% of donors have type A blood, what is the probability that it will take at least 4 donors to find one with type A blood? The histogram below displays the results of a simulation of selecting 4 people and checking their blood type. The simulation was repeated 100 times. For example, the number in the "0" bin is the number of times that no donors out of 4 were selected. Predict what will happen to the shape of the histogram when the probability changes.
