Answer 4

you can think of probability as a fraction of the favorable outcomes to the total outcome.

probability = favorable / total

here we want complement of 4, which means the numbers which are not 4 .

Answer 5

Probability = # favorable / # total .

here the event we want is 'not' getting 4. there are 5 ways of not rolling a four, 1,2,3,5,6.
so the numerator of the fraction is 5. the denominator is the total ways of rolling a die
1,2,3,4,5,6.
so we have probability = 5/6
