Answer 1

Solution: 1 Mark for probabiltiy of an odd number.
1 Mark for probabiltiy of an even number.


Number of times an odd number was rolled = 15 + 36 = 51
Probability of rolling an odd number = 51/100 = 0.51
Number of times an even number was rolled = 33 + 16 = 49
Probability of rolling an even number = 49/100 = 0.49.
