You randomly draw a marble from a bag of marbles that contains8 blue marbles, 5 green marbles, and 8 red marbles. What is \text{P(draw a blue or red marble})P(draw a blue or red marble)start text, P, left parenthesis, d, r, a, w, space, a, space, b, l, u, e, space, o, r, space, r, e, d, space, m, a, r, b, l, e, end text, right parenthesis? If necessary, round your answer to 222 decimal places.

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

i have not got your picture clearly so see it once again

secant-secant formula:

(whole secant) x (external part) =           (whole secant) x (external part)

(8+y-2) *8=                                           (y+4+6) *6

(y+6)*8 = (y+10) *6

distribute

8y+48 = 6y +60

subtract 6y from each side

2y +48 = 60

subtract 48 from each side

2y = 12

divide by 2

y = 6

sv =     (y+4+6)

sv   = 6+4+6

sv = 16
