If you roll a die 30 times how many times would you expect to roll a 1 why

5 times because 30/6 is 5 and there is one one 1 side of the six sided die (1/6)

If it's a fair die, and there are 6 possible outcomes out of 30 throws, it becomes a fraction. 30/6 which = 5. So you are expecting every number to come out 5 times. The answer is 5 :)

Then just do it (lol)
