which rule of probability

[erod09]

i have been trying to use the multiplication rule for probability and i thought i was suppose to multiply each percentage by two but it does not look like anything we did in class and i can't figure it out. is there a better formula?

95% of the people order pizza. 65% order salad.?
find the probability that a person who orders pizza will also order a salad. I am not sure if I should be using the multiplication rule for probability. any help would help. thank you

Assume 100% of the people order one or both the items. Then use Venn diagram.
