    The percentage 'y' of impurities per batch in a certain chemical product is a beta random variable with probability density

    f(y)={90y^8(1-y) if 0<=y<=1
    0 elsewhere

    *90 is above 0 in enclosure

    What are the values of alpha and beta?

    Because, Beta random variable has the distribution as,
    <br>
    <br>f(x) = x^(a - 1) (1-x)^(b - 1)/Beta(a,b)
    <br>here, a is actually ALPHA ...
