You will take either a basket weaving class or a philosophy class, depending on what your advisor decides. You estimate that the probability of getting an A in basket weaving is 0.35 (it is a hard class), while in philosophy your probability of getting an A is 0.84. However, your major is straw construction, and the chance of your advisor choosing the philosophy class is only 40%. What is the probability that you get an A? The probability that you get an A is (Give the exact simplified probability.)
