Question

Suppose 3 of a dozen oranges are bruised and 2 are chosen at random from the dozen. The probability that both are bruised is?

Answer 1

Is it going to be 3/12? I'm not sure

Answer 2

The probability is 1/12

We have given that total number of oranges=3 dozen

There are 12 oranges in a dozen

n=3(12)=36 oranges

We have to choose 2 from dozen

so the probability for 2 from 12 is

What is the formula for probability?

Probability = total number of outcome in A/total number of outcome in n

Therefore,

Probability=2/36=1/12

Therefore we get the probability is 1/12
