In this question, we're asked to consider the experiment of tossing a coin three times.
00:07
In part a, what they want us to do is to develop a tree diagram for the experiment.
00:14
So let's start off our tree diagram.
00:17
So we know that the first time we toss the coin, we are either going to get heads or tails.
00:22
So we have heads, and then done here we have tails.
00:27
And this is t1.
00:28
T1, we can call it t1, gets us right here.
00:34
Now, if we were to move this down a bit, we know we have to toss it a second time.
00:46
So, assuming we toss it again when we get heads, we're either going to get heads or tails.
00:55
And if we toss it again, when we get tails, we are either going to get tails or heads.
01:03
And this is the result of toss to.
01:07
Now, for our final toss, we can see that all of the last toss.
01:13
All of them are going to give us either heads or tails.
01:19
So heads or tails, heads or tails, heads or tails, and heads are tails.
01:28
And that's tos 3.
01:31
So this is going to be our tree diagram for the experiment.
01:36
In part b, they want us to list the experimental outcomes...
