Question

A cooler contains 7 cans of​ soda; 3 ​colas, 3 ​orange, and 1 cherry. Two cans are selected at random without replacement. Find the probability that at least one can is orange.

Answer 1

P(NOT Orange)=(4/7)(3/6)

P(NOT Organge)=2/7

P(O>0)=1-2/7

P(O>0)=5/7

So the probability of at least one orange can is 5/7
