Question

A and B are the only two outcomes of an event. Probability P(A) = 0.3 then what will be the probability P(B) ?​

Answer 1

Answer:

P(B) = 0.97

Step-by-step explanation:

The sure event of of any outcome is 1

So,

we have two outcomes of an event A and B.

So, P(A) = 0.3

=> P(A) + P(B) = 1

=> 0.3 + P(B) = 1

=> P(B) = 1 - 0.3

=> P(B) = 0.97
