A and B are independent witnesses.
Probability A speaks the truth = $x$,
Probability B speaks the truth = $y$.
If both agree on a statement, the probability that the statement is true is:
1
2
3
4
Solution
Both agree and the statement is true: Probability = $xy$
Both agree but the statement is false Probability = $(1-x)(1-y)$
So required probability:
$\dfrac{xy}{xy + (1-x)(1-y)}$
