Problem
If one person has a 25% chance of getting a disease by age 70, what is the probability of one in a group of 4 getting cancer by that age? I am thinking it should be 1/4 * 4, but that does not seem right to me either.
The solution depends on what is meant by "probability of one in a group of 4".
The response should include a reference list. Using double-space, Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
