A forest consists of two types of trees: those that are 05 ft and those that are taller than 5 ft. Each year, 40% of all 05-ft tall trees die. 10% are sold for $20 each, x% stay between 0 and 5 ft, and y% grow to be more than 5 ft. Each year, 50% of all trees taller than 5 ft are sold for $50, 20% are sold for $30, and 30% remain in the forest. What is the probability of eventually selling a tree that is taller than 5 ft. for $30? two decimals
