Help (How do I enter my solution?)
Combination
"A choose B". Enter: Aob or AüB (Example: 10o2 or 10ü2 =
)
Factorial
Enter: a! (Example: 5! = 1*2*3*4*5)
Exponent
Enter: a^b (Example: 2^3 = 23)
Addition
Enter: a+b (Example: 2+3)
Multiplication
Enter: a*b (Example: 2*3)
Division
Enter: a/b (Example: 2/3)
Percent
Percent numbers are automatically converted to decimal numbers.
Enter: a% (Example: 2% => 0.02)

Enter your solution
- You can enter your answer as a formula, or you can enter your final calculated result.
- Bitte gib deine Lösung auf 3 signifikante Nachkommastellen genau (gerundet) ein.
-
Dabei bedeutet ‚signifikant‘: Wenn die Lösung ≥ 1.0 ist, dann 3 Nachkommastellen, richtig gerundet.
Wenn die Lösung < 1.0 ist, dann in e-Notation umwandeln mit einer Stelle vor dem Komma und 3 (signifikanten)
Stellen nach dem Komma, richtig gerundet.
Beispiele:- 1.23456789 = 1.235
- 0.04352876 = 4.353e-2
- 0.00012386 = 1.239e-4

Question 1 / 5
Binomial
Formula:
Properties of the Binomial
Expected value μ = E(X) = n*p
Variance σ² = Var(X) = n*p*q = n*p*(1-p)
Hypergeometric distribution
Formula:
Properties of the Hypergeometric distribution
Expected value μ = E(X) = 
Variance σ² = Var(X) = 
Inclusion-exclusion principle
Two quantities
|A ∪ B| = |A| + |B| - |A ∩ B|
Three quantities
|A ∪ B ∪ C| = |A| + |B| + |C| - |A ∩ B| - |A ∩ C| - |B ∩ C| + |A ∩ B ∩ C|
