The table shows the results of spinning a four colored spinner 50 times. find the experimental probability and express it as a decimal. p(not blue)=?

color red blue green yellow
# of times spun 20 10 9 11
(1 point)
a. 0.1
b. 0.4
c. 0.8
d. 0.2
i need

Option: C is the correct answer.

               P(not blue) is:

          C.  0.8

The results of the experiments on spinning a colored spinner 50 times is:

Color                   Red    Blue    Green     Yellow

# of times spun     20      10          9             11      

This means that the total number of outcomes=50

and the number of outcomes which are not blue is the outcome such that spin is red, green and yellow.

i.e. Number of outcomes which are not blue=20+9+11

                                                                        = 40

Hence, the P(not blue) is the ratio of the number of outcomes which are not blue to the total number of outcomes.

i.e.   P(not blue)=40/50=4/5=0.8

        Hence, option: C is the answer.

                    C.  0.8
