Math 3322 Chapter 9 Equations for Exams

 

P(A) = n(A)                             0 < P(A) < 1                P(A U B) = P(A) + P(B) – P(A h B)

            n(S)

odds in favor of A = P(A)/[1 - P(A)]                          odds against A = [1 – P(A)]/P(A)                  

If odds in favor of E are m:n, P(E) = m/(m + n)

P(B|A) = [P(A h B)]/P(A)                                 E = a1 . p1 + a2 . p2 + a3 . p3+  … + an . pn

nPr = n!/(n – r)!                                    Permutation of like objects= n!/(r1! .r2! .r3! . …  .rk!)

nCr = n!/[r!(n – r)!]

nC r =  n!/[r!(n-r)!]

1o = 1/360 of a complete circle rotation

1 radian = 1

The sum of the measures of the exterior angles (one at each vertex) of a convex polygon is 360o

The sum of the measures of the interior angles of any convex polygon with n sides

= (n – 2)180o

The measure of a single interior angle of a regular n-gon = (180on – 360o )/n

V + F = E + 2                          n(n-3)/2 = d, number of diagonals of a convex polygon
