    Probability

    1.) A card is drawn at random from a normal 52 card deck.

    a.) Find the probability if getting a heart: I got 13/52 = 1/4
    b.) Find the probability of not getting a heart: I got 3/4
    c.) Find the probability of getting a spade or a club: I got 1/2

    2.) From the word INTUITION:

    a.) Find the probability of getting a vowel: I got 5/9
    b.) Find the probability of getting a consonant: i got 4/9
    c.) Find the probability of getting an E: I got 0

    3.) There is a total of 600 students at a school. 425 students study accounting and 350 study economics.

    a.) Find the probability that if a student is selected at random he studies economics only: i got 1/4

    b.) Find the probability that a student studies neither accounting nor economics: i got 1/24
