If you roll a number cube 12 times, about how many times would you expect NOT to roll a 5 or 6?

So 6 number total

5 and 6 are 2 so

6-2=4

find probaility of NOT roling is disired outcomes/total possible outcomes so

disired=4

total possible=6

4/6=2/3

so 2/3 times out of 12 you would not roll a 5 or 6 so

2/3 times 12=24/3=8

8 is the naswer
