Question

If A is an event of a random experiment such that P(A): P(A)=5:11 than find . P(A) andP(A),

Answer 1

According to the given ratio, the total number of events from the experiments is equal to the sum of the ratios which is 5 + 11=16

Probability = number of outcomes / total number of outcomes.

P(A) for the first one is 5/16 meaning the number of outcomes or rather events is equal to 5.

P(A) for the second one is 11/16 meaning the number of outcomes or events is 11.

Answer 2

Answer:

Step-by-step explanation:

Let p(A) =5x

And p(/A) =11x (/A is Probability of not A)

We know p(A) +p(/A) =1

Thus 16x=1

X=1/16

p(A) =5/16

p(/A)=11/16

There is no need to verify as we have got the answer by the theorem p(A) +p(/A) =1
