Math Problem Statement
Hannah is playing a game with her friend Brenda where they flip a coin and then throw a dice. Brenda wins if a head is flipped and a number above 2 is rolled. Hannah wins if a tail is flipped and a number 2 or more is rolled. A. Draw a tree diagram to show all possible outcomes.
Solution
To draw a tree diagram for this game, we need to account for all the possible outcomes from flipping the coin and rolling the dice. Here's how we can break it down:
- Coin Flip: There are two possible outcomes: Head (H) or Tail (T).
- Dice Roll: For each coin flip outcome, there are 6 possible dice outcomes: 1, 2, 3, 4, 5, or 6.
Thus, the total number of outcomes is possible combinations.
Steps to create the tree diagram:
- Start with a branch for the coin flip, which splits into two: H (Head) and T (Tail).
- For each coin flip outcome, branch out into 6 more branches representing the dice rolls: 1, 2, 3, 4, 5, and 6.
The game rules are as follows:
- Brenda wins if a head is flipped and a number above 2 is rolled.
- Hannah wins if a tail is flipped and a number 2 or more is rolled.
Now, I'll describe how the tree diagram would look:
- From the starting point, draw a branch labeled H (Head) and another branch labeled T (Tail).
- Under each of these, create 6 branches corresponding to the dice outcomes: 1, 2, 3, 4, 5, 6.
- For H (Head): label the branches 1, 2, 3, 4, 5, 6.
- For T (Tail): label the branches 1, 2, 3, 4, 5, 6.
Outcome Summary for the Tree:
-
H (Head) → 1: Not Brenda’s win.
-
H (Head) → 2: Not Brenda’s win.
-
H (Head) → 3: Brenda wins.
-
H (Head) → 4: Brenda wins.
-
H (Head) → 5: Brenda wins.
-
H (Head) → 6: Brenda wins.
-
T (Tail) → 1: Not Hannah’s win.
-
T (Tail) → 2: Hannah wins.
-
T (Tail) → 3: Hannah wins.
-
T (Tail) → 4: Hannah wins.
-
T (Tail) → 5: Hannah wins.
-
T (Tail) → 6: Hannah wins.
Visual Representation:
plaintextStart / \ H(Head) T(Tail) / \ / | | | | \ 1 2 1 2 3 4 5 6 | | | | | | | (No) (No) (No) (Yes) (Yes) (Yes) (Yes) (Yes) (Yes) (Yes) (Yes)
- (No) means neither player wins.
- (Yes) means the corresponding player wins (Brenda or Hannah).
Would you like more details on the rules or any other clarification?
Here are some related questions:
- What is the probability that Hannah wins the game?
- How can you calculate the odds of Brenda winning the game?
- What if the dice had only 4 sides instead of 6? How would the tree change?
- What’s the probability that either player wins the game in this scenario?
- Can this game be modified so that both players have an equal chance of winning?
Tip: Always break down the problem into smaller steps, like splitting coin flips and dice rolls into branches in a tree diagram, to better understand the possible outcomes.
