In my questions 'n' and 'p' are given to me but I'm not sure how to find 'x', I'd like to know how to find it, so in your response could you please tell me how you did it.

1. n = 6, p = 0.35 find P (at least 3 successes)

2. n = 100, p = 0.01 find P (no more than 3 successes)

Oh ya and this question is supposed to be done on a graphing calculator

Thanks
