Carol has 5 scarves and 5 sweaters, each scarf matches a different sweater . If she chooses one of theses scarves and one of these sweater at random, what is the probability that they will not match?
@Yagamisumit319,
p(match) =1/5
therefore p(no match) = 4/5
NB in a 5 x 5 sample space, 5 squares out of 25 will represent a match
