Answer:
See below.
Step-by-step explanation:
1.
2a + 3 * (1 + 2) = 2a + 9: Yes. Expression is equivalent.
2.
33v = (3 * v) * 11: Yes. Expression is equivalent.
3.
3b - 19 + 2b = 3b + 19 - 2b: No. Both expressions are different answers.
4.
4(3c - 4) = 2(6c - 8): No. expressions are not equivalent.
P(Y1 | R2) = P(Y1R2)/P(R2)
P(R2 | Y1) = 4/9 ..........P(Y1) = 1/3
P(R2 | B1) = 1/2 ..........P(B1) = 2/9
P(R2 | R1) = 3/8 ..........P(R1) =4/9
P(R2) = [4/9*1/3] + [1/2*2/9] + 3/8*4/9] = 23/54
P(Y1R2) = P(Y1)*P(R2|Y1) = 1/3*4/9 = 4/27
P(Y1 | R2) = 4/27*54/23 =8/23

-4 2/5 / -5
-4 2/5 = -22/5
-5 = -5/1
-22/5 / -5/1
Flip -5/1 to multiply
-22/5 x 1/-5
Numerator x numerator / denominator x denominator
-22 x 1 = -22
5 x -5 = -25
-22/-25 = 22/25
The answer is 22/25.
