The same friend discussed in this module who claimed to have special psychic powers now claims to have an extraordinary palate as well. She claims that she can tell the difference between store-brand peanut butter and name-brand peanut butter by taste alone. You put her claim to the test. Ten days in a row, you give her identicalsized portions of four different kinds of peanut butter—one store brand and three name brands. If she is just guessing and really cannot tell the difference, what is the probability that she will be able to pick out the store brand from the name brands on at least 6 of those 10 days?
