Math Problem Statement
In a garden, 40% of the flowers are roses and the rest are carnations. If 25% of the roses and 10% of the carnations are red, find the probability that a red flower selected at random is a rose.
Solution
This problem requires the application of Bayes' Theorem to find the probability that a randomly selected red flower is a rose. We are given:
- 40% of the flowers are roses, meaning and the rest are carnations, so .
- 25% of the roses are red, meaning .
- 10% of the carnations are red, meaning .
Step 1: Calculate the total probability of selecting a red flower.
We use the Law of Total Probability to compute , the probability that a flower is red:
Substitute the values:
Step 2: Use Bayes' Theorem to find the probability that a red flower is a rose.
Bayes' Theorem is given by:
Substitute the known values:
Thus, the probability that a randomly selected red flower is a rose is 0.625 or 62.5%.
