Need Probability/Statistics help So, I don't understand probability at all! I am feeling so hopeless right now. If anyone can help me with how to solve a couple of questions, I'll be eternally thankful! Any help will be greatly appreciated! Here are the questions: 1. Consider the events A and B, where P(A)=2/5, P(B')=1/4 and P(A U B)=7/8. (a) Write down P(B). (b) Find P(A and B) (c) Find P(A|B). and The heights of boys at a particular school follow a normal distribution with a standard deviation of 5 cm. The probability of a boy being shorter than 153 cm is 0.705. (a) Calculate the mean height of the boys. (b) Find the probability of a boy being taller than 156 cm.
