Question

if A is an event of a random experiment such that p(A) :p(Ā) =5:11 then find p(A) and p(Ā), verify p(A) +p(Ā)=1

Answer 1

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..

Answer 2

Answer:

Step-by-step explanation:

P(ā)=1- P(a)

P(ā)=1-0.05

P(ā)=0.95
