By the age of 1, many infants display a tendency to favor one hand over the other. About 70% favor their right hands, about 20% favor their left hands, and the rest show no preference yet. Suppose 3 unrelated, year-old infants are observed at a day care center. What's the probability for each of the following? (a) none show any preference (b) all show a preference for one hand or the other (c) all show a preference for the same hand (a) About % of infants show no preference of one hand over the other. (Simplify your answer.) The probability of none of the infants showing any preference is (Simplify your answer. Type an integer or a decimal.) (b) About % of infants show preference of one hand over the other. (Simplify your answer.) The probability of all infants showing a preference for one hand or the other is (Simplify your answer. Type an integer or a decimal.) and the probability of all infants showing preference for the left hand is (c) The probability of all infants showing preference for the right hand is (Simplify your answers. Type integers or decimals.) The probability of all infants showing a preference for the same hand is al Enter your answer in each of the answer boxes
