To play a game, a number cube with sides numbered 1 through 6 is rolled and a fair coin is flipped.
aleksley [76]

Answer:

16.7%

Step-by-step explanation:

Please check below attachment for sample space table

Firstly, we have the total number of possible results as 12

From the 12, the probability of flipping a head is 6/12

Rolling either a 3 or a 5 is the sum of places we have both divided by the possible total of 12

we have this as ;  2/12 + 2/12 = 4/12

The term ‘AND’ means we have to multiply the two probabilities as follows;

4/12 * 1/2 = 1/6 = 0.1667

To the nearest tenth, we have this as 16.67% which is 16.7%

If r = 9, b = 5, and g= −6, what does (r + b − g)(b + g) equal?
r-ruslan [8.4K]

Answer:

-20

Step-by-step explanation:

(r + b − g)(b + g)

we have fom statement:

r = 9    

b = 5

g= −6

so we have:

(r + b − g)(b + g)= (9+5-(-6))*(5+(-6))

(r + b − g)(b + g)= (14+6)*(-1)

(r + b − g)(b + g)= -20

Find f(-2) if f(x)=-x^3+2x^2+x-1
ser-zykov [4K]

Answer:

f(- 2) = 13

Step-by-step explanation:

To evaluate f(- 2) substitute x = - 2 into f(x)

f(- 2) = - (- 2)³ + 2(- 2)² + (- 2) - 1

        = - (- 8) + 2(4) - 2 - 1 = 8 + 8 - 2 - 1 = 13
