let x be a random variable having u(0,10) distribution and y = x - [x], where [x] denotes the greatest integer less than or equal to x. then p(y > 0.25) equals?

I would suggest making a graph. Then start plotting some points and try to figure out what the graph of y looks like. Once you do that honestly you should be able to figure the values for x that give you y>0.25. When you have that all you need to do is figure out the probability of X falling in that set of values.
