Well... how many times is it possible for it to land on a 6, if you roll it 4 times?

The dice could land with a 6 up 0 times, once, twice, thrice or 4 times. That's all you're being asked to find out.
To calculate the probability of it landing two or three times you need to use binomial distribution, as the other ones are pretty simple to work out.
