किसी घटना के होने व ना होने की प्रायिकता का योग?
a) 2
b) 1
c) 0
d) none of this​

Answer 1

Answer:

1

Probability of an event+ probability of not happening of that event =1

Answer 2

OPTION (B.) 1

Step-by-step explanation:

The sum of the probabilities of all outcomes must equal 1 . If two events have no outcomes in common, the probability that one or the other occurs is the sum of their individual probabilities. The probability that an event does not occur is 1 minus the probability that the event does occur.

(event+not even=1)
