20 out 50 rolls of a number cube resulted in a 2 being rolled. based on this information, if the cube was rolled 220 times, how many rolls of a 2 could be expected?

88 times

Step-by-step explanation:

The two comes up 20 out of 50 times

We don't know how many times 2 will come up if the die is rolled 220 times. We can, however, set up a proportion

20/50 = x/220                    Cross multiply

50x = 20 * 220                   Combine the right

50x = 4400                         Divide by 50

50x/50 = 4400/50             Do the division

x = 88   times.

answer: a.   one is a factor of every whole number since every number is divisible by itself.
