When Alexa takes her 1st free throw in a game, she has a 40 percent chance to score. She has a 70 percent chance of scoring on her next throw if she scored on the earlier one, but only a 20 percent chance if she didn't score on the previous one. Assume she needs to make 3 free throws in a row, the first of which she misses. What is the probability that she will score at least once on one of the following two throws?
