Which is more likely?
A: You roll two dice 5 times and, every time, one of the two comes up as 1 and the other as 6.
B: You roll 10 dice all at once. 5 come up as 1s and the other 5 come up as 6s.
Assume the dice are standard, six-sided, and fair.
How are the two situations similar? How are they different?
