The probability of selecting a black marble on the first draw is 0.5. What is the probability of selecting a yellow marble on the second draw, given that the first marble drawn was black? A)0.28
B)0.56
C)0.64
D)0.78

i dont know

step-by-step explanation:

is there any photos or whatever?

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
