Please help me figure out how to do this. I'm usually okay at math but I am at a loss with this.
You draw nine cards from a standard deck of cards. What is the probability that
a. four or more will be red,
b. exactly two or three will be red,
c. two or fewer will be red, and
d. exactly five will be red?
I am assuming the 9 cards were drawn at once without replacing them.
