Suppose that two different tests A and B are to be given to a student chosen at random from a certain population. Suppose that the mean score on test A is 85 with a standard deviation of 10; the mean score on test B is 90 with a standard deviation of 16; the scores on the two tests have a bivariate normal distribution; and the correlation of the two test scores is 0.8. If the student's score on test A is 80, what is the probability that their score on test B will exceed 90
