Question

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?

Answer 1

88

Explanation:

Answer 2

88 times

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.
