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.
How many ways can yo pick two numbers from the list? 7 C 2 = 21 ways to pick two numbers
only ONE combination , multiplied = 196 (2 x 98)
one out of twenty one ways = 1/21
