A spinner is evenly divided into eight sections: three are red, three are white and two are green. If the spinner is spun twice, then the probability of getting the same color twice is

the probability of getting the same color twice is

Given :

A spinner is evenly divided into eight sections: three are red, three are white and two are green.

Total of 8 sections.

red=3

white =3

green =2

Probability of getting two red color =

Probability of getting two white colors =

Probability of getting two green colors=

Probability (getting same color twice)=

11/32

Step-by-step explanation:

Given that:

Red section (R) = 3 ; white section (W) = 3 ; green section (G) = 2

Total Number of sections = 8

Probability of getting the same color on two spins :

Probability = (required outcome / Total possible outcomes)

Either P(RR) or P(WW) or P(GG)

(3/8 * 3/8) + (3/8 * 3/8) + (2/8 * 2/8)

9/64 + 9/64 + 4/64

(9 + 9 + 4) / 64

22 / 64

= 11/32
