Using the probability concept, the correct statement is:
B. P(hibiscus|red) = P(hibiscus).
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
For item a, the probabilities are:
- P(yellow|rose) = 45/105 = 0.4286.
- P(yellow) = 135/315 = 0.4286.
Same probabilities, hence the statement that they are different is false.
For item b, the probabilities are:
- P(hibiscus|red) = 80/120 = 2/3.
- P(hibiscus) = 210/315 = 2/3.
Equal, hence this is the correct statement.
