Q17.A teacher observes that the cumulative distribution function (CDF) for the scores on a mathematics test is F(x)=⎩⎨⎧0,x2,1,x<0,0≤x≤1,x>1. For 0≤x≤1, where x is the score normalized to 1. If a student scores above 0.7, what is the conditional probability that they actually score above 0.9? Enter the answer correct to two decimal places.
