Answer is Option (c) 1
Example :-
Probability of getting head in one toss of a coin = 1/2
Probability of getting tail in one toss of a coin = 1/2
Sum of probability of events = 1/2 + 1/2 = 2/2 = 1
Example :-
Probability of getting head in one toss of a coin = 1/2
Probability of getting tail in one toss of a coin = 1/2
Sum of probability of events = 1/2 + 1/2 = 2/2 = 1
