Question

In a class, the probability that a randomly chosen student likes dogs is 0.72, that a student likes cats is 0.54, and that a student likes neither is 0.11. Find the probability that a student likes both dogs and cats.

Answer 1

.72+.54-x = 1-.11

Answer 2

Pentagon MNOPQ is inscribed in a circle, NO=OP=PQ and MN=MQ. If angle NMQ=96°, find angle NPM.

Answer 3

If the center is C, then we know that angles
NCO = OCP = PCQ = 64°
because each subtends an equal side, and their sum is 2*96°.

Se where that takes you.
