Let X be random variable with probability density function
`f(x)={{:(2/x^(3), x ge 1), (0, x lt 1):}`
Which of the following statement is correct

A continuous random varibale X has probability density function f(x)=kx^(2) 0 le x lt 1 find k P(1 lt x lt 5)

A continuous random varibale X has probability density function f(x)=kx^(2) 0 le x lt 1 find k find P(X lt 5)

The random variable X has the probability density function f(x)={{:(ax+b, 0 lt x lt 1), (0, "otherwise"):} and E(X)=7/12 , then a and b are respectively

X is continuous random variable with probability density function f(x)=(x^(2))/(8),0 le x le 1 . Then, the value of P(0.2leXle0.5) is
