Question
Each spinner is divided into four equal sectors (1-4). The pointer in each spinner, when spun, is equally likely to rest in any one of the four sectors. The pointer in each spinner is spun once. What is the probability that the sum of both scores is less than five

Make a table for the two spins
X| 1 2 3 4
---------
1| 2 3 4 5
2| 3 4 5 6
3| 4 5 6 7
4| 5 6 7 8
Out of the 16 possible outcomes, count how many satisfy the given condition, and divide this number by the number of possible outcomes.

Each spinner is divided into 5 equal sectors. (Two separate spinners) The pointer in each spinner, when spun, is equally likely to rest in any one of the 5 sectors. The pointer in each spinner is spun once. List the sample space and find the probability that the sum of both scores is:
a) odd
b) Even
c) At least 7
d) Less than 7
