It is possible to score higher than 1600 on the combined mathematics and reading portions of the SAT, but scores 1600 and
above are reported as 1600. Suppose the distribution of SAT scores (combining mathematics and reading) in 2019 was
approximately Normal with mean of 1021 and standard deviation of 214.
What proportion of SAT scores for the combined portions were reported as 1600? That is, what proportion of SAT scores were
actually higher than 1600? Give your answer to four decimal places
