We're told that



a. We want to find
. By definition of conditional probability,

By the law of total probability,

Then

(the first equality is Bayes' theorem)
b. We want to find
.

since
.
The correct answer is A<B+1
The answer is 3
.............
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}
