There are two possibilities

Orange then green or green the orange

The probabilities are:

P(o&g) = 2/10*2/9 = 2/45
P(g&o) =2/10*2/9 = 2/45

Required probability is:

Evaluate each expression for g = -7 and h = 3 and match it to its value. 1. g + h 2 2. g - h 46 3. h - g -21 4. gh -4 5. g + h2

Ivanshal [37]

Answer:

1. -4

2. -10

3. 13

4. -21

5. 2

6. 46

Step-by-step explanation:

To evaluate the expression, substitute g= -7 and h = 3. Then simplify using order of operations.

1. $g-h = -7 + 3 = -4$

2. $g-h = -7 - 3 = -10$

3. $h-g = 3 - -7 = 3+10 = 13$

4. $gh = -7(3) = -21$

5. $g+h^2 = -7 + 3^2 = -7+9 = 2$

6. $g^2-h = (-7)^2 -3 = 49 -3 = 46$
