Answer:

Not necessary

Step-by-step explanation:

If you mean Probability of event 'a' by the term p(a),

We should always remember that the sum of 'all' the probabilities is 1.

If this is a case of 2 choices(e.g. A Coin toss), then yes p(a)=0.3

But if this is a case of 3 or more probabilities (e.g. Die roll), then it is not necessary.

In other terms, the given statement is true only when p(a) union p(b) is 1.
