Would need to know the all the options that you would be drawing from... I would think they are overlapping because a star is a shape and purple. disjoint/independent formula : P(A)*P(B)= P(AandB)
OpenStudy (anonymous):
do you know the overlapping formula @mscooper
OpenStudy (anonymous):
P(A or B) = P(A) + P(B) - P(A and B)
