If a fair dice is tossed 10 times - what is the probability of at least 2 6's?

What is the general 'formula', say I want at least 4 6's etc..

Thanks

Let X be the random variable

*number of 6's*.

X ~ Binomial(n = 10, p = 1/6).

Calculate .

Use the formula given here: Binomial Distribution (1 of 3) - Dec 17th 2008, 05:22 AMlorenz
