Answer:

60%

Explanation:

probability = number of favorable outcomes /number of outcomes

There are four prime numbers from 1 to 10

There are 5 even numbers from 1 to 10

Therefore in one roll of the dice there is a 40% (4/10)probability that Rob would win and there is a 60%(1-0.40) probability that Amy would win

If the dice is rolled 4 times, the probability that Amy has more points than Rob remains 60%
