Wile E. Coyote is pursuing the Road Runner across Great Britain toward Scotland. The Road Runner chooses his route randomly, such that there is a probability of 0. 8 that he'll take the high road and 0. 2 that he'll take the low road. If he takes the high road, the probability that Wile E. Catches him is 0. 1. If he takes the low road, the probability he gets caught is 0. 5
