Three-person leadership committee from a pool of eight qualified candidates = 8C3 = 56
If a committee has Aly and Ben then the other member can be any of the other 6.
If a committee has Cam and Dan then the other member can be any of the other 6.
56-6-6 = 44 valid committees.
44/56 = 11/14
X=11 and Y=14

Total ways to organize = 8c3 = 56
If AB are selected together, there will be 6 invalid committees, i.e., ABC, ABD, ABE, ABF, ABG, ABH
If CD are selected together, there will be 6 invalid committees, i.e., ACD, BCD, CDE, CDF, CDG, CDH
Therefore, 56 - 6 - 6 = 44 valid committees.
x = 44 = 11
y = 56 = 14
Answer, x/y = 11/14

Probability = Valid/Total
Total = 8C3 = 56
Novalid = 6 (Aly, Ben, X), X has 6 possible values + 6 (Cam, Dan, X), X has 6 possible values = 12
Valid = Total - Novalid = 56 - 12 = 44
Probability = 44 / 56 = 11 / 14
X is 11
Y is 14
Total = 8C3 = 56
Novalid = 6 (Aly, Ben, X), X has 6 possible values + 6 (Cam, Dan, X), X has 6 possible values = 12
Valid = Total - Novalid = 56 - 12 = 44
Probability = 44 / 56 = 11 / 14
X is 11
Y is 14

The good committees probabilities is complimentary to the bad ones, so I will calculate the bad ones and subtract those probabilities from 1.
the probability of picking A is 1/8 and then the probability of picking B is 1/7. You can Pick A first and then B and vice versa, so as the probability of picking A is independent of the one of picking B the combined probability is their multiple - 2 * 1/8 * 1/7 = 1/28
Another bad committee is picking C and then D or vice versa, which is the same probability as above, so we get 1/28.
The bad committees will either be of the first or the second type, so we add the probabilities to get 1/28 + 1/28 = 2/28 = 1/14.
1- 1/14=13/14
