Two octopi, Inky & Octi, are being kept in two separate cages in a laboratory. Being the clever creatures that they are, Inky has a 73% chance of escaping from his cage and Octi has a 20% chance of escaping. There is an 18% chance that both octopi escape. Let "O" = the event that Octi escapes and "I" = the event that Inky escapes.

A.) Find the probability at least one of the two octopi will escape

B.) If Octi escapes, find the probability that Inky will not escape
