We are shown a spinner that has 1, 2, 3, 4, 5, 6, 7, 8, 9 equal parts, and it wants us to determine the probability of each of these scenarios.
00:12
So the first one is landing on a 1 or a 4.
00:16
We have 1, 2, 3, 4 of those, so that would be 4 over 9.
00:22
The next one is landing on a 1, so that happens two times, so that would be 2 over 9.
00:32
Not landing on a 2 would be everything but a 2, so that would be, since there's only one 2, 8 over 9.
00:42
Landing on a 4 would be 2 over 9.
00:50
Not landing on a 2, is that not the same as this one? okay, so that's the exact same one.
00:59
This could be 8 over 9.
01:03
Landing on a 3, 1, 2, 3, 4 over 9...
