Question: Let q be a normally distributed continuous random variable with a mean of 3 and a standard deviation of 0,5. Let r represent the number

Let q be a normally distributed continuous random variable with a mean of 3 and a standard deviation of 0,5. Let r represent the number of successes over a large number of trials where we expect, on average, to get 6 successes. Let s be the sum when three 4-sided dice are rolled. What's the probability that: (a) both q and r are less than 3.9? (b) s is more than 9? (c) q is more than 3 or s is less than 8? (d) both r and s are not equal to 5?
