Suppose that 55% of all adults regularly consume coffee, 65% regularly consume carbonated soda, and 75% regularly consume at lea
st one of these two products. (a) what is the probability that a randomly selected adult regularly consumes both coffee and soda? (b) what is the probability that a randomly selected adult doesn't regularly consume at least one of these two products?
4^-3 would be 1/64 since you flip the 4 over when you have a negative power and 4^5 would be 1024 (4 x 4 x 4 x 4 x 4) so your final answer would be 16 because you have to divide 1024 by 64
