Having difficulty with these questions from my one of my modules
In a certain population women have weights which are Normally distributed with a mean of 50kg and a standard deviation of 5kg. Men have weights which are Normally distributed with a mean of 70kg and a standard deviation of 10kg.
A) Find a weight w to the nearest 0.1kg such that both men and women would have an equal probability of having a weight between w and w+1 kg.
B) How many points of equal probability are there?
