Brianna has a bag of colored tiles. Without looking, she removes one tile, records the color, and replaces it She repeats this process 40 times and records the results in the table. What is the probability that Brianna will not pick a yellow tile on her forty first time? Write your answer as a fraction in simplest form. Use the / as your fraction bar.

7/8

Step-by-step explanation:

N(S)=40

P(not getting yellow)=N(R)+N(B)+N(G)/N(S)

=9+12+14/40

=7/8

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
