I need help with B ASAP because work is due tomorrow and Im seriously stuck. I have tried so many, please help.

Part A is correct; good job.

The universe is even numbers between 1 and 25, that's 2 thru 24. Count; there are twelve of them.

There's only one of them in the intersection of A and B, namely 8.

So the probability is one in twelve.

1/12

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
