Question

Two brown-eyed parents are told that there is a 25% probability that their baby will have blue eyes.

a) What are the odds in favor of such parents having a baby with blue eyes? 2 marks
b) What are the odds against? 1 mark

Answer 1

Explanation:

To calculate odds, divide the probability that the event will occur by the probability that it doesn't occur. In other words, odds= p/(1-p)

a.) .25/(1-.25) = 1/3

b.) .75/(1-.75)= 3
