A florist has roses, tulips, and daisies in a basket. If one flower is selected at random for a bouquet, what is the probability that the selected flower is a tulip?
A
B
C
D
Verified step by step guidance1
First, determine the total number of flowers in the basket by adding the quantities of each type: roses, tulips, and daisies.
Express the total number of flowers as \$5 + 3 + 2$ to find the sum.
Identify the number of tulips, which is given as 3.
Set up the probability formula for selecting a tulip: \(\text{Probability} = \frac{\text{Number of tulips}}{\text{Total number of flowers}}\).
Substitute the values into the formula: \(\frac{3}{5 + 3 + 2}\) and simplify the denominator to get the final probability fraction.
