What is the probability that a bottle chosen at random is Coke?
What is the probability that a bottle chosen at random is either Pepsi or IBC?
(a)
To calculate: The probability that a bottle chosen at random is Coke, if a cooler contains
Answer to Problem 13CT
Solution:
The probability that a bottle chosen at random is Cokeis
Explanation of Solution
Given information:
A cooler contains
Formula used:
The formula to find probability for any event
Calculation:
To calculate the probability that a bottle chosen at random is Coke, first calculate total number of bottles in a cooler.
A cooler contains
Thus, the cooler contains total
Out of those 20 bottles,
Thus,
Therefore, the probability that a bottle chosen at random is Coke is
(b)
To calculate: The probability that a bottle chosen at random is either Pepsi or IBC. if a cooler contains
Answer to Problem 13CT
