A bag contains seven balls, which are numbered one to seven.
00:00:05.460 --> 00:00:08.630
Determine the sample space of choosing a ball at random.
00:00:10.560 --> 00:00:14.550
A sample space is the set of all possible outcomes.
00:00:16.880 --> 00:00:22.720
In our case, we have a bag that contains seven balls; these balls are numbered from one to seven.
00:00:23.420 --> 00:00:28.390
We’re gonna choose one at random, and we wanna know what is the sample space.
00:00:28.470 --> 00:00:30.910
What is the range of outcomes here?
00:00:32.310 --> 00:00:37.640
We know that no matter what, we’re gonna choose a number from one to seven.
00:00:39.490 --> 00:00:44.400
Our sample space is a list, a set, of all the possible outcomes.
00:00:44.580 --> 00:00:53.810
Here, we can have one, two, three, four, five, six, or seven, no more or no less; these are our only options.
00:00:55.450 --> 00:00:58.050
These range of options create our sample space.
