what about. Skip rolls a six sided die ten times and gets a 1 every time. What is the probability that on the eleventh roll he will roll a three?



1/11
5/6
1/6

mathsolver · Answer

Ok, so the previous rolls do not affect what side the dice is going to turn up on next. since there are 6 sides and one must assume an equal probability for each side then 1/6 is your answer

oh so just because the previous rolls were all 1s that doesnt affect it?

mathsolver · Answer

not at all
