Answer:
0.74
Step-by-step explanation:
A <u>tree diagram</u> is a visual way of showing combinations of <u>two or more events</u>. The outcome of each branch is labelled at the end of the branch line and its probability is written alongside the branch.
To calculate the probabilities of each combination, follow the branches and <u>multiply the probabilities</u> together.
There are two possible combinations to get a final outcome of D:
- A and D = 0.6 × 0.7 = 0.42
- B and D = 0.4 × 0.8 = 0.32
Therefore, the probability of D is:
⇒ P(D) = P(A and D) <u>OR</u> P(B and D):
⇒ P(D) = 0.42 + 0.32
⇒ P(D) = 0.74
Answer:
Step-by-step explanation:
We are given,
The fraction of money spent on a product = 
.
Since, we have that,
20 = 4 × 5
Simplifying this equation to get the required fraction i.e. , we get,
