If the difference between the probability of success and failure of an event is 5/19. Find the probability of sucgess and failure of the event.

Then, according to the question,

p-q = 5/19…(i)

Also, we know that, p + q = 1

On adding Eqs. (i) and (ii), we get

Hence, the probability of success is 12/19 and the probability of failure is 7/19
