Suppose that one card is to be selected from a deck of 20 cards that contains 10 red cards numbered from 1 to 10 and 10 blue cards numbered from 1 to 10. Let A be the event that a card with an even number is selected, let B be the event that a blue card is selected, and let C be the event that a card with a number less than 5 is selected. Describe the sample space S and describe each of the following events both in words and as subsets of S
a. A ∩ B ∩ C
b. B ∩ Cc
c. A U B U C
d. A ∩(B U C)
e. A c ∩ Bc ∩ Cc
