1. Which statement is incorrect for outcomes when 2 coins are tossed?
a) The outcome of first coin doesn’t affect the outcome of second coin
b) The outcome of second coin doesn’t affect the outcome of first coin
c) If outcome of first coin is head then the outcome of second coin cannot be head

2. If 2 dice are rolled, which of the following cannot be the sum of the numbers on the 2 dice?
a) 12
b) 1
c) 2
d) 6
View Answer
Explanation: A die has 6 faces. The faces are numbered 1, 2, 3, 4, 5 and 6. When a die is rolled, there are 6 outcomes. When 2 dice are rolled, possible outcomes are 36 as below:
(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)
(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)
(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)
(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)
(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)
(6,1) (6,2) (6,3) (6,4) (6,5) (6,6).
Thus, the sum of 2 dice can be a number between 2 and 12. It can never be 1.
3. Which of the below is an invalid outcome when 3 coins are tossed?
