Suppose that for a group of consumers, the probability of eating is 0.75 and that the probability of drinking Coke Further suppose that the probability of eating pretzels and drinking Coke is 0.55. Are these two events independent? Why?

If I have interpreted your question correctly (and that might not be the case), the events are not independent.

Explanation:

If the first event was meant to be:
"(the probability of) eating and drinking Coke (is #0.75#)"

then "eating and drinking Coke" is a subset of "eating pretzels and drinking Coke"
and therefore these are not independent events.
