A jar contains 5 blue marbles, 2 black marbles, and 7 brown marbles. Event A = drawing a brown marble on the first draw
Event B = drawing a blue marble on the second draw
If two marbles are drawn from the jar, one after the other and not replaced, what is P(B|A) expressed in simplest form?

A. 2/7
B. 5/14
C. 5/13
D. 6/13

i belive those are the ones that are under 90 degreese.

addition

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
