Here we're given a coin that is tossed three times, and we want to find the probability and the amount of outcomes for three events.
00:13
So a, we have exactly one head.
00:18
B, we have a head on the first two tosses.
00:27
And then c, we have a tail on the first and last.
00:33
So when looking at our sample space, we know that for each of the tosses, we have two outcomes, which means in total, there are eight, because we multiply it two, three times.
00:47
So let's go ahead and write our outcomes.
00:52
We have three heads, heads, heads, tail, heads, tails, head, and tail, head, head.
00:59
Then we have three tails, tails, tails, head, tails, heads, tail, and then head, tail, tail...
