Let Y be a random number between 0 and 1 generated by an idealized random number generator. Find the following probabilities:
A. P (0 less than equal to Y less than equal to .6) =?
B. P (.3 less than equal to Y less than equal to .5) =?
C. P ( Y less than equal to .2 or .7 less than equal to Y) =?
PLEASE HELP!!! THANK YOU SOOOO MUCH! :)

an experiment consists of 4 tosses of a coin.denoting the outcomes HHTH,THTT,..and assuming that all 16 outcomes are equally likely, find the probability distribution for the total number of heads.
