Hey im having some problems with probability and here are the two homework questions.

1)What is the probability that you will pass a test and get at least 4 questions correct by randomly guessing on each question of a 6 question quiz multiple choice quiz with 5 choices for each question.

2) Every year at least 5 million people die of tobacco related causes, assume that the distribution is normal with a population mean of 5 million and a standard deviation of 2 million...find the probability that more than 4 million people will die of tobacco related causes and find the 75th percentile of the distribution of tobacco related deaths.

any help is appreciated!
