Answer:
[tex]\dfrac{4}{15} \approx \bold{0.267}[/tex]
Step-by-step explanation:
Given that:
Number of lemon - lime flavored bottles = 8
Number of orange flavored bottles = 7
Bottles are picked one by one.
First for the friend and then for the person himself.
To find:
The probability that both the bottles drawn are of lemon-lime flavor.
Solution:
Total number of bottles available in the cooler = 8 + 7 = 15
Formula for probability of an event E can be observed as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
[tex]P(First\ lemon-lime) = \dfrac{8}{15}[/tex]
Now, lemon - lime flavored bottles left = 7
Total number of bottles left = 14
[tex]P(Second\ lemon-lime)=\dfrac{7}{14}[/tex]
Required probability:
[tex]P(Both\ lemon - lime) = \dfrac{8}{15}\times \dfrac{7}{14}\\\Rightarrow P(Both\ lemon - lime) = \dfrac{4}{15} \approx \bold{0.267}[/tex]
