Hey Donmarco.

The first thing you should look at is what the definition is. We know Type I error is P(H1 retained|H0 correct) while Type II is P(H0 retained|H1 correct) = 1 - P(H1 retained|H1 correct).

So now we need to know what the hypotheses are to get a specific value: what are your hypotheses for this particular example?
