First department can choose the pair (delegate,alternate) by 7*6 = 42 ways.
Second department can choose the pair (delegate,alternate) by 10*9 = 90 ways.
Third department can choose the pair (delegate,alternate) by 6*5 = 30 ways.
Since these selections are INDEPENDENT, the resulting choice can be done in 42*90*30=113400
Answer:
10/30 multiplied by 9/29 equals 90/870
P(two yellow cards) = 3/29
