when using the probability multiplication rule without replacement, does the top number of the fraction go down one each time?

for example:

	McDonald's	Burger King	Wendy's	Taco Bell
order accurate	329	263	249	145
order not accurate	33	54	31	13

'If two orders are selected, find the probability that they are both from Taco Bell.' a. assume that the selections are made with replacement. b. assume that the selections are made without replacement.

==> a. (158/1118)(158/1118) = .02 b.- IS THE CORRECT WAY TO SOLVE THIS: (158/1118)(158/1117) OR (158/1118) (157/1117)
