Question
Three rotten apples are accidentally mixed with twelve good ones. One apple is picked at random. What is the probability that it is a good one?
Solution
No. of Good apples - 12, No. of Rotten apples - 3, Total No. of apple - 15
P(Good apple) = `("No. of Favourable Outcomes")/("Total no. of outcomes")`
`= 12/15`
`= 4/5`
