Step-by-step explanation:
Step 1 :
Given
Number of people choosing Juice A = 37
Number of people choosing Juice B = 32
Number of people choosing Juice C = 21
We need to find the odds in favor of choosing a person who chooses juice A
Step 2 :
Here the number of success is the number of people choosing juice A = 37
Number of failures is the number of the people not choosing juice A = Number of people choosing juice B + Number of people choosing juice C = 32+21 = 53
Hence the odds in favor of choosing a person who chooses juice A is 37:53
