IIFT 2021 (23rd Dec)
For both Ishika and Mishika to agree on a statement either both have to speak the truth or both have to speak false.
Probability of both speaking truth = (60/100)*(85/100) = 204/400
Probability of both speaking false = (40/100)*(15/100) = 24/400
The probability that the statement is true when Ishika and Mishika both agree on a statement = (204/400)/{(204/400)+(24/400)} =
204/228 = 51/57
