(A messy version of the table above)
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 red) = ?
0.6
0.4
0.2
0.3
Ah forget it with that table!
red: 20
blue:10
green:9
yellow:11
p(not red) = (50-20)/50 = ?
*Sigh*
0.6, sadly I did the quiz, and put another answer.Thanks for the help though :-)

put the answer in fractions
The total number of spins is 6+4+3+5 = 18.
The number of times the spinner landed on blue is 4.
So, the experimental probability of the spinner landing on blue is:
4/18
This can be simplified to:
2/9
Therefore, the experimental probability of the spinner landing on blue is 2/9 as a fraction.
To find the experimental probability of an event, you need to divide the number of favorable outcomes by the total number of outcomes. In this case, we want to find the probability of not getting red, so the favorable outcomes would be the number of times the spinner landed on blue, green, or yellow.
Counting the number of times the spinner landed on each color:
- Red: 20 times
- Blue: 10 times
- Green: 9 times
- Yellow: 11 times
To find the total number of outcomes, you need to add up the number of times the spinner landed on each color:
Total outcomes = 20 (red) + 10 (blue) + 9 (green) + 11 (yellow) = 50
Now, we can find the probability of not getting red by considering the favorable outcomes (blue, green, and yellow) and dividing it by the total number of outcomes:
P(not red) = (10 + 9 + 11) / 50 = 30 / 50 = 0.6
So, the experimental probability of not getting red, expressed as a decimal, is 0.6.
