Three coins are tossed.
The sample space is: S = {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT}
Event E = three heads show
E = {HHH}
Event F = exactly two heads show
F = {HHT, HTH, THH}
Event G = three tails show
G = {TTT}
Now,
E, F and G are mutually exclusive events.
But,
E, F and G are not exhaustive.
Hence, events E, F and G are mutually exclusive, but not exhaustive.
An experiment involves rolling a pair of dice and recording the numbers that come up. Describe the following events:
A : The sum is greater than 8.
B : 2 occurs on either die.
C : The sum is at least 7 and a multiple of 3.
Which pairs of these events are mutually exclusive?
Two dice are thrown. The events A, B, C are as follows:
A = Getting an odd number on the first die.
B = Getting a total of 7 on the two dice.
C = Getting a sum ≥ 8 on the two dice.
Describe events:
(i) A' (ii) not B (iii) A or B (iv) B and C (v) A but not C (vi) B but not C (vii) B or C
Two dice are thrown. The events A, B and C are as follows:
A: getting an even number on the first die.
B: getting an odd number on the first die.
C: getting the sum of the numbers on the dice ≤ 5
State whether the following is true or false (give reason for your answer):
A and B are mutually exclusive.

A: getting an even number on the first die.
B: getting an odd number on the first die.
C: getting the sum of the numbers on the dice ≤ 5
State whether the following is true or false (give reason for your answer):
A and B arc mutually exclusive and exhaustive.
