Question 1204279:  1. Let a coin and a die be tossed; let the sample space S consists of the twelve elements: 
S={H 1, H 2,H 3 , H 4, H 5 ,H 6,T 1 ,T 2 ,T 3 ,T 4 ,T 5,T 6} 
a. Express explicitly the following events: 
i. A= {heads and an even number appear} 
ii. B= {a prime number appears} 
iii. C= {tails and an odd number appear} 
b. Express explicitly the event that: 
i. A or B occurs. 
ii. B andC occurs. 
iii. Only B occurs. 
. c. Which of the events A,B and C are mutually exclusive?

S={H 1, H 2,H 3 , H 4, H 5 ,H 6,T 1 ,T 2 ,T 3 ,T 4 ,T 5,T 6}
 
a. Express explicitly the following events:
 
i. A= {heads and an even number appear}
 
A = {H 2, H 4, H 6, T 2, T 4, T 6}
 
ii. B= {a prime number appears}
 
B = {H 2, H 3, H 5, T 2, T 3, T 5}
 
 
iii. C= {tails and an odd number appear}
 
C = {T 1, T 3, T 5}
 
 
b. Express explicitly the event that: 
i. A or B occurs.
 
AU B = {H 2, H 3, H 4, H 5, H 6, T 1, T 2, T 3, T 4, T 5, T 6}
 
ii. B andC occurs.B n C = {T 3, T 5}
 
 
iii. Only B occurs. 
Event B from above
 
. c. Which of the events A,B and C are mutually exclusive?
 
Find the intersection set of A B, BC, and AC.
 
If you find any of intersection set empty then they are mutually exclusive
