Question

What is the probability of the outcome (not A)? a. 0.3 c. 0.8 b. 0.5 d. 0.15

Answer 1

Answer: b. 0.5

Step-by-step explanation:

We area given that the probability of outcomes A = 0.5

We know that for any event Q the probability of not getting Q is given by :-

$P(Q)'=1-P(Q)$

Now, the probability of getting outcomes not A is given by :-

$P(A)'=1-P(A)\\\\\Rightarrow\ P(A)' =1-0.5\\\\\Rightarrow\ P(A)' =0.5$

Hence option B is correct.
