For question B, it asks for the probability of there being 2 girls or more, so wouldn't the lower boundary be 2 girls with the upper being 6?

[@angie2208]

You can do it both ways since they produce the same answer

[@araksi7404]

exactly my thoughts, it should work i think

Hi, I am currently using T1 84 Plus CE, but now I am having difficulties using bionomcdf on this calculator because it shows different answer to others. Do you know why this is happening?

[@OSC1990]

Not sure what the problem is for you - perhaps ask your teacher? When using binomcdf or binompdf, make sure you're 100% clear on which one you should be using. BinomPdf is for 'exactly r successes', whereas BinomCdf is for 'up to r successes'.
