a flower vase contains 8 red roses, 10 white daisies, 6 yellow carnations, and 12 yellow daisies. a single flower is selected at random. what is the probability that the flower selected is yellow or is a daisy? express your answer as a simplified fraction. enter your answer in the box.
Answer
Explanation:
Step1: Calculate total number of flowers
$8 + 10+6 + 12=36$
Step2: Calculate number of yellow flowers
$6 + 12=18$
Step3: Calculate number of daisies
$10 + 12=22$
Step4: Calculate number of yellow - daisies
$12$
Step5: Use the addition rule of probability
$P(\text{yellow or daisy})=\frac{18 + 22-12}{36}=\frac{28}{36}=\frac{7}{9}$
Answer:
$\frac{7}{9}$
