Need help on binomial distribution question

So for this question I wrote down the binomial distribution correctly, but then I did 1 - P(X<=2) (using the binomial CD setting on my calculator) and got 0.104, which is wrong. Can anyone please explain why my method didn’t work, and/or where the 0.01465 + 0.00098 comes from?

More than 3 is >=4 and the complement of that is <=3.

P(X>3) Would be the same as 1 - P(X<=3) so thats probably where your mistake is. I think the MS has just done P(X=4) + P(X=5) which should give the same answer
