V125BC [204]

We're told that

P(A)=\dfrac1{200}=0.005\implies P(A^C)=0.995

P(B\mid A)=0.7

P(B\mid A^C)=0.05

a. We want to find P(A\mid B). By definition of conditional probability,

P(A\mid B)=\dfrac{P(A\cap B)}{P(B)}

By the law of total probability,

P(B)=P(B\cap A)+P(B\cap A^C)=P(B\mid A)P(A)+P(B\mid A^C)P(A^C)

Then

P(A\mid B)=\dfrac{P(B\mid A)P(A)}{P(B\mid A)P(A)+P(B\mid A^C)P(A^C)}\approx0.0657

(the first equality is Bayes' theorem)

b. We want to find P(A^C\mid B^C).

P(A^C\mid B^C)=\dfrac{P(A^C\cap B^C)}{P(B^C)}=\dfrac{P(B^C\mid A^C)P(A^C)}{1-P(B)}\approx0.9984

since P(B^C\mid A^C)=1-P(B\mid A^C).

Plato wonders of these triangles are congruent.
yanalaym [24]

Answer:

Step-by-step explanation:

∠D ≅ ∠R

DC ≅ RK

So, If ∠C ≅ ∠K,

Then ΔDCS ≅ ΔRKO  by   Angle Side Angle congruent.   {A S A}

OR

DC ≅ RK

∠D ≅ ∠R

If SD ≅ OR , then

ΔDCS ≅ ΔRKO   by Side Angle Side   congruent  {S A S}
