If A speaks the truth 80% of the times, B speaks the truth 60% of the times. What is the probability that at least one will tell the truth  Choose the correct choice from the following:
A) 0.8	B) 0.92	C) 1.02	D) 1.2	E) 1.3
probability of A speaks truth p(A)=8/10;false=2/10   probability of 0.92 speaks truth p(0.92)=6/10;false=4/10.For given qtn   Ans=1-(neither of them tell truth).0.92ecause A &amp; 0.92 are independent events   =1-[(2/10)*(4/10)]=1-8/10=1-0.08=
