Let the probability distribution function (pdf) for a continuous random variable be defined as f(x) = 1 for 0 < x < 1. What is E[X]?     0     0.10     0.25     0.33     0.50     0.67     0.75     1     None of the above.

Continuous random variables 6. A charity group raises funds by collecting waste paper. A skip-full will contain an amount, X of other materials such as plastic bags and rubber bands. X may be regarded as a random varibales with probability density funnction. All nmerical values are in units of 100kg. Find the Expected value and Standard deviation.Express your answer in 3 decimal place value f(x)= - c(x-1)(4-x) 0 for 1

The pdf of a random variable X is given by: f(x) = 0.2e-0.2x for x > 0 Please find P(x < 1). 0.4512 0.3297 0.8187 0.1813
