Continuous random distribution
The continuous random variable X has pdf f(x)=x/2, 0<=x<=2. Two independent determinations of X are made. What is the probability that both these determinations will be greater than one? If three independent determinations had been made,what is the probability that exactly two of these are larger than one?
