What do you think?
No. You are probably not going roll a 2 six times in a row.
Huh? Can anyone else help?
Ms. Sue, can I have some help? I think 6 is the answer because there are 6 sides?
But only one of those sides has a two.
Prob(rolling a two) = 1/6
number of expected times of getting a 2 in 6 rolls
= 6(1/6) = 1
number of expected times of getting a 2 in 6 rolls
= 6(1/6) = 1
