If two distinct members of the set\{ 2, 4, 12, 14, 21, 28, 98 \} are randomly selected and multiplied, what is the probability that the product is a multiple of 196? Express your answer as a common fraction.

There's no magic to this.

There are 7 pairs that multiply to a multiple of 196.

There are 21 unordered pairs that can be made from the set.

P[product is a multiple of 196]=7/21 = 1/3
