Determine the number of outcomes that compromise or comprise the specified event.
00:06
So the number of hours needed by a sixth graded students to complete a research project was recorded with the following results.
00:14
And so i've tabulated those here.
00:16
Four hours was 22, five hours was 21, six hours was 17, seven hours was 11, eight hours was 10, nine hours was six, and more than 10 hours was five.
00:30
So we have two different events.
00:32
A, at most eight hours, and b, at least eight hours.
00:36
And we want to know how many different outcomes there are for that.
00:40
So let's start with a.
00:41
At most eight hours.
00:43
That means eight or less.
00:46
So which ones are eight or less? that's going to be these right here...
