Answer to A:

50%

Explanation for A:

We're looking for how many numbers are odd, so theres 1, 3, 5 ,7, four numbers.

We have a total of 8 numbers.

\frac{4}{8} = 0.5

To make any number a percent we move the point over to the right by two, which makes our final answer 50%

Answer to B:

37.5%

Explanation for B:

If the number is less than four, that means we need to find if it will roll the first three numbers. We, once again, have eight total possibilities

\frac{3}{8} = 0.375

0.375 can be turned into our final answer, 37.5%
