Assertion (A): In probability, the sum of probabilities of all possible outcomes of an event is always 1.
Reason (R): Probability of an impossible event is always 1.
Solution:
Assertion (A) is TRUE. In probability theory, the total probability of all outcomes in a sample space is always 1.
Reason (R) is FALSE. The probability of an impossible event is 0, not 1.
Thus:
· A is true
· R is false
