Answer
239/275 and 36/275
Work Step by Step
First, you have to create a table from that shows the "handedness", "frequency", and "probability distribution". By adding the two numbers together (478 and 72 which equals 550) you will have gotten the total. Thus, you will then know the probability distribution for left hand (239/275) and for right hand (36/275). Remember that the relative frequency is the probability distribution.
