Paige rolls a number cube sixty-four times. the number 4 comes up fourteen times. the number 3 comes up six times. rounded to the nearest whole percent, what is the experimental probability of rolling a 3 or 4?

To determine the probability of obtaining 3 or any number in a roll, we divide the number of outcomes with the sample space.
            probability of 3 :    n = 6/64 = 3/32 = 0.09375
            probability of 4 :    n = 14/64 = 7/32 = 0.21875
Since, we use the conjuction "or", we therefore add up these probabilities. 
                      n = 5/16 or 0.3125
