Suppose that there are two identical looking coins lying on

Suppose that there are two identical looking coins lying on the table. One is fair and the other is loaded, so that the coin flips heads 70 percent of the time. Choose a coin and flip it once. Construct a tree diagram that shows the probability outcomes.

COINS FAIR LOADED TAIL HEAD TAIL HEAD PROB 0.5 0.5 PROB 0.3 0.7 PROBABILITY OF CHOOSING FAIR COIN IS 0.5 AND LOADED COIN IS 0.5
