a.

b.

c. By the law of total probability,

According to the inclusion/exclusion principle,

but by DeMorgan's law,

So

and from there we find

d. The event of having at most two of these defects is complementary to the event that all three defects occur simultaneously:

Right triangle ... use Pythagorean theorem.
Hypotenuse is longest side.
8^2 = 64 so it is the shortest side, then sqrt(95) then sqrt(150).
So Pythagorean theorem is 8^2 + [sqrt(95)]^2 = [sqrt(150)]^2 if the triangle is right.
64 + 95 = 159 which doesn’t equal 150 so he’s right. It’s not a right triangle
