Statistics - Binomial Distribution
Fichas del conjunto (4)
- 1Binomial Distribution- n independent trials (results don't depend on previous results)
- 2 possible outcomes: P = success, Q = Failure
-If these conditions are met: X ~ B (n,p)
(X is binomially distributed with n trials and p probability) - 2FormulaIf the conditions are met, the formula is:
P(x=r) = nCr x p^r x q^n-r - 3ExpectationIf X ~ B (n,p) , expectation = np
- 4QuestionsX ~ B (10,0.7)
p(x=1) = 10C1 x (0.6)^1 x (0.3)^10
= 0.0001381
p(x>1) = p(x=2) = p(x=3) .... p(x=10)
1 = p(x=0) + p(x=1) + p(x>1)
p(x>1) = 1 - p(x=0) - p(x=1)
= 0.9999
