Butterflies: • Alice, Bob, and Charlotte are looking for butterflies. They look in three separate parts of a field, so that their probabilities of success do not affect each other. • Alice finds 1 butterfly with probability 17%, and otherwise does not find one. • Bob finds 1 butterfly with probability 25%, and otherwise does not find one. • Charlotte finds 1 butterfly with probability 45%, and otherwise does not find one. Let X be the number of butterflies that they catch altogether. A) Find the expected value of X. B) Write X as the sum of three indicator random variables, X1,X2,X3 that indicate whether Alice, Bob, Charlotte (respectively) found a butterfly. Then X=X1+X2+X3. Find the expected value of X by finding the expected value of the sum of the indicator random variables.
