Question

A father claims about snowfall last night. First daughter tells that the probability of snowfall on a particular night is 1/8. Second daughter tells that 5 out of 6 times the father is lying! What is the probability that there actually was a snowfall

Answer 1

2.08%

Explanation:

The probability of a snowfall on any given night is 1/8.

The probability that the father is telling the truth is 1 - 5/6, or 1/6.

Then:

1/6 x 1/8=1/48=0.0208, or 2.08% ............
