Question

Sort the events in increasing order of the no. of sample points (Event with least number of sample points at the top).

• A. Tossing 2 coins
• B. Rolling 2 dices
• C. Rolling of a die
• D. Tossing 3 coins

Answer 1

The outcomes on tossing two coins are: (HH, TT, TH , HT).
So, the total number of outcomes = 4.

The outcomes on rolling a die is: (1, 2, 3 , 4, 5, 6)
So, the total number of outcomes = 6.

The outcomes on tossing three coins are: (HHH, TTT, THH , THT, TTH, HTH, HHT, HTT).
So, the total number of outcomes = 8.

The outcomes on rolling two dices are:
(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)
So, the total number of outcomes = 36.
