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
The answer is d. if they are chemically joined as a mixture is multiple element but they aren't chemically joined. And an atom is what the element is made of and a solution is not anything to do with joined elements
