Solution

The correct option is A
0.41

Number of questions with answer as "true" = 59
Number of questions with answer "False" = 41

Probability of an event $E$ , $P (E) = \frac{N u m b e r o f f a v o u r a b l e o u t c o m e s}{N u m b e r o f t o t a l p o s s i b l e o u t c o m e s}$
So, the probability of the answer being false $= \frac{41}{100} = 0.41$
