Suppose that 53.2% of all car owners are male
12.7% of all owners change their own oil
If 31.5% of male car owners change their own oil what is the probability that a randomly selected car owner is male and changes his own oil.

You'll never pass the test if you cant figure it out on your own.

ETA - I'm pretty sure you've screwed something up in your OP. If 31.5% of males change their own oil, and males are 53.2% of car owners, there is no way only 12.7% of car owners change their own oil. The math doesn't check out.

Oh, and the chance that some that changes their own oil is male is 100%.

Dropping the little bits
30% of 50 is 15.
15 is more than 12.7
Therefore your whole thread is bogus.
