please answer when you have to calculate P(x>4) is it is it not 1- P(x<=4)? .) The probability density function of the random variable X is given by: [ce-2 f(x) = for a > 0 otherwise. For what value of c is this a legit density function? Find the value for c, then calculate calculate P(x>4) so rather than calculate P(x>4) can 1- P(x<=4)?
