G For a and c being constants, the distribution of the size of claims paid under an insurance policy is a continuous random variable with a probability density function of ( ) a f x c x   for 0 5  x . For a randomly selected claim, the probability that the size of the claim is less than 3.75 is 0.4871. Calculate the probability that a randomly selected claim is greater than 4. Give your answer as a decimal rounded to four places (i. e. X.).
