1 One out of every three boxes of cereal has a
prize in it. To find the experimental probability
that the next box he buys will have a prize, Joe
rolls a number cube 50 times. He lets a multiple
of 3 represent a box with a prize and all other
numbers represent a box without a prize. His
results are shown in the table to the right. What
is the experimental probability that Joe's next
box will have a prize in it?
