Answer 1

Answer:

Option: C is the correct answer.

               P(not blue) is:

          C.  0.8

Step-by-step explanation:

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

Answer 2

Blue is 10 and all the numbers added together is 50 so it would be 4/5 because 1/5 chance is blue so the rest isnt blue
