Hi, would appreciate some help with the following problem.
The following probabilities are for a person having the respective blood types.
0.45- type O
0.40- type A
0.11- type b
0.04- type ab
among four potential donors what is the probability that they are not all Type A
I did .4*.4*.4*.6 but that seems wrong as the answer is pretty small. How would I calculate this probability?
