							Class Participation Exercise. Probaility


1. You are given a 2 headed coin. What is the probability of tossing heads; ... of
tails?
             P(H) = _____.            P(T) = _____.


2. Given a straight deck of cards, What is the probability of:

a. P(any red odd numbered card) = _____.         b. P(face card any suit) = _____.
c. P(any black card 6 or less) = _____.


3. Examine the common elements in your answers to the coin and card
problems. Based on these observations you can infer that the probability for any
single finite event equals ___________________________________________.


4. Given a die (not a dice pair) and 3 coins in a sack (a penny, nickel and dime),
a. the odds of rolling a 5 with the die and selecting a nickel from the sack are?

P(5) = ______        P(nickel) = ______          P(5 and a nickel) = _______

b. the odds of rolling a even number with the die, selecting a dime from the sack
and tossing a tails with the coin drawn from the sack are?

P(even) = ______            P(dime) = ______            P(tails-coin) = ______

                     P(even and dime and tails-coin) = ______.
