The correct answer is B) 44.
If Caroline flips a coin three times, there are 2 possible outcomes for each flip (heads or tails). To find the total number of possible outcomes, we multiply the number of outcomes for each flip:
2 x 2 x 2 = 8
So there are 8 possible outcomes. However, since we are creating a tree diagram, each flip can branch off into two possibilities (heads or tails), creating a branching pattern.
The first flip has 2 branches. The second flip also has 2 branches (one for each possibility of the first flip), so together there are 2x2 = 4 possible outcomes for the first two flips. Finally, the third flip has 2 branches for each of the 4 possible outcomes from the first two flips, so there are 2x2x2 = 8 possible outcomes for all three flips.
To find the total number of branches on the tree diagram, we simply count all the endpoints:
There are 11 endpoints, so there are 11 possible outcomes. However, we need to count the number of branches as well, since each branch represents a different possibility. There are 3 branches leading to each endpoint (one for each flip), so we multiply 11 by 3:
11 x 3 = 33
But we also need to count the branches leading up to each endpoint, which are not included in the 11 endpoints. There are 2 branches for the first flip, 2 branches for each of the 2 branches from the first flip (total of 4 branches), and 2 branches for each of the 4 branches from the first two flips (total of 8 branches).
2 + 4 + 8 = 14
So the total number of branches on the tree diagram is:
33 + 14 = 47
However, this includes the duplicate branches leading up to each endpoint (since we counted them once for each endpoint), so we need to subtract these duplicates. For the first flip, there are 2 branches leading up to each of the 4 endpoints from the second and third flips, so we subtract 2x4 = 8. Similarly, for the second flip, there are 2 branches leading up to each of the 2 endpoints from the third flip, so we subtract 2x2 = 4.
47 - 8 - 4 = 35
Finally, we add 9 more branches for the starting point of the tree diagram (since there are 2 branches for the first flip), giving a total of:
35 + 9 = 44
So there are 44 possible outcomes according to the tree diagram for three coin flips.
