I have the following two problems and I don't know how to approach them.(adsbygoogle = window.adsbygoogle || []).push({});

A cookie jar has 3 red marbles and 1 white marble. A shoebox has 1 red marble and 1 white marble. Three marbles are chosen at random without replacement from the cookie jar and placed in the shoebox. Then 2 marbles are chosen at random without replacement from the shoebox. What is the probability that both marbles from the shoebox are red?We talked about payoffs, Simple and Compound Growth,Conditional Probability, Law of total probability, Baye's Theorem. Simple math is obviously not enough, I need to prove it using those topics we covered. I'm not quite sure how to approach those problems. Any input? A fair coin is tossed n times, where n is an even integer. What is the probability that the number of heads exceeds the number of tails?

Thank you
