Question

Steve has 12 biscuits in a tin.

There are 7 digestive, 2 chocolate and 3 ginger biscuits.
Steve takes two biscuits at random from the tin.
Work out the probability that he chooses two different types of biscuits.

Answer 1

Answer: 7/12 and 3/12

Step-by-step explanation: There are 12 biscuits, so let's take the digestive biscuits and the ginger biscuits.

There are 3 ginger biscuits out of all the 12 biscuits so 3/12 or 3 out of 12

Now let's do the digestive, there are 7 digestive out of all 12 biscuits, 7/12 or 7/12
