Question

A coin is tossed and a number cube a rolled. What is the probablity that the coin shows tails and the die shows a 1 or a 2 ?

Answer 1

Coin - 1/2 Probability 
Dice - 1/6 Probability 
1/2 Multiplied by 1/6 = 1/12 
Your probability that a tail and the number one will show is 1 out of 12

Answer 2

The sample space for this event is {H1,H2,H3,H4,H5,H6,T1,T2,T3,T4,T5,T6}
There are 12 possibilities.
The probability that we get a T1 or T2 is 2/12 or 1/6.
