Question

Ram speaks truth in 3/4 of cases and shyam in 4/5 of cases. in what percent of cases while narrating the same event are they likely to contradict each other?

Answer 1

2 percent im not sure about it

Answer 2

Answer:

35%

Step-by-step explanation:

Assume that Ram = a, Shyam = b.

p(a)=3/4,p(a lies)=1-3/4=1/4

p(b)=4/5,p(b lies)=1-4/5=1/5

a & b Contraduct each other = [a lies & b true]or[b true & a lies]

=p(a).p(b lies) + p(a lies).p(b)

=(3/4*1/5)+(1/4*4/5)=7/20

=(7/20*100)%=35%
