Robin tosses two number cubes 100 times and gets a pair of 3s 18 times. What is the experimental probability that she will roll a pair of 3s on her next toss?

The experimental probability is the ratio of the number of times the event occurred to the total number of trials. In this case, Robin rolled a pair of 3s 18 times out of 100 trials, so the experimental probability is:
18/100 = 9/50
So the answer is (C) 9:50.
