n = 14 e p = 0,60, find P(X < 9)

P(X < 9) = 1 - P(X > 9) ????

No, P(X < 9) means all the values of X that X can take that is less than nine, excluding 9. This means you have X = 0, 1, 2, 3, 4, 5, 6, 7, 8.

But for P(X > 9), you have X = 10, 11, 12, 13, 14.

But 1 - P(X > 9) incluse the values of X = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

which is not equal to P(X < 9) - June 20th 2010, 12:49 PMchisigma

If I have 11 elements, is easy calculate

P(X<9) = 1 - P(X>=9)

I can ? - June 20th 2010, 02:21 PMSpringFan25
