(a.) What is the probability that both will weigh more than 70 pounds?
(b.) What is the probability that one of the children will weigh more than 65 pounds and the other will weigh less than 59 pounds?
(c.) Assume that a school bus can hold 36 children and has a maximum weight capacity (excluding the driver) of 2340 pounds. Assume that 36 randomly selected children board the bus. What is the probability that the total weight of these children will exceed the weight capacity of the bus?
Here is my answer:
the probability of one kid weighing more than 70 pounds
The solution uses a z score to find out the percentage or probability.
