Question 1019078: You roll a pair of dice 20 times and record how often you get a total of 5 or 10. What is your best guess for the relative frequency that this event (a total of 5 or 10) occurs without seeing the actual data?
Give your answer as a proportion, rounding to three decimal places.

A total of five comes up 1/9 of the time.
A total of ten comes up 1/12 of the time.
The probability of getting a five or a ten is
1/9 + 1/12 = 7/36
7/36 times 20 rolls is almost four times...
A third way to express this is
7%2F36+=+x%2F20
and
x = 3.889
