    Question

    A generator of random numbers in a computer will spread its outcomes spread evenly over the entire interval from 0 to 1 when we make it generate a long series of numbers. We call this a so-called uniform distribution. A generator of random numbers produces a number X that lies in an interval between 0 and 0.4 or in an interval between 0.7 and 1, what is the probability of P(X ≤ 0.4 or X > 0,7)?


    1. FALSE: 0,4
    2. FALSE: 0,7
    3. TRUE: 0,3
    4. FALSE: 1,1

    1. 0,4: Incorrect
    2. 0,7: Incorrect
    3. 0.3: Correct
    4. 1.1: Incorrect
