A basketball player has an 80% chance of making the first free-throw he shoots. If he makes the first free-throw shot, then he has a 90% chance of making the second free-throw he shoots. If he misses the first free-throw shot, then he only has a 70% chance of making the second free-throw he shoots. Suppose this player has been awarded two free-throw shots. Find the probability that he makes at least one of the two shots

(x/2) + 1 = -5add -1 to both sides
x/2 = -5 - 1
x/2 = -6 multiply both sides by 2
x = -6 * 2
x = -12
