Question

External probability

Answer 1

The answer above is right

Answer 2

The correct answer option is 0.8.

Explanation:

We are given the results of spinning a four colored spinner 50 times and we are to find the experimental probability of not getting a blue (in decimal).

Number of times blue spinner is spun = 10

Total number of times spinner is spun = 50

P (not blue) =
`1 - \frac { 1 0 } { 5  0 } = 1 - \frac { 1 } { 5 } =(4)/(5)` = 0.8
