Given that P(BA) means the probability of event B occurring given that event A will occur or has occurred, which of the following correctly calculates this probability? A) P(B)
B) P(A and B)/P(B)
C) P(A)/P(B)
D) P(A and B)/P(A)​

D

Step-by-step explanation:

the answer is d because b and a have to happen at the same time

step-by-step explanation:

their are no angles. sorry cant .

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
