There are 5 houses with number greater than 14. At least 2 means 2 or 3 of these houses are chosen for the newspapers.
Probability will be 5/12 for first one, 4/11 for second one as one less in total will be there, and so on.
If 2 are delivered then two will be from these 5 and 1 will be from the remaining 7. This can be done in 3 ways as the third house can be any of these three.
Multiply 3 by 5/12,4/11 and 7/10.
Another way is if all three are from these 5 houses. In this case, 5/12 for first one, 4/11 for second, 3/10 for the third, multiply them.
Then add both values to get the total probability.

Can you help me with mine?
