Statistics for Business: What is the probability at least two students will fail?

It is estimated that 10% of those taking the quantitative methods portion of the CPA examination fail that section. Sixty students are taking the exam this Saturday. (Use the normal approximation to the binomial distribution.)

What is the probability at least two students will fail? (Round z-score computation to 2 decimal places and your final answer to 4 decimal places.)

I know for sure that the answer is not 0.9862 because I am able to check my work before submitting, but I don't know what else it could be. Please help. Need the answer today because it is due tonight. Thanks.
