The table shows the result of spinning a four-colored spinner 50 times. Find the experimental probability and express it as a decimal

P(not red)

Color RED BLUE GREEN YELLOW
Times Spun 20 10 9 11

A. 0.6
B. 0.4*****
C. 0.2
D. 0.3

your answer is P(red)

the question is P(not red)

the two probabilities sum to 1
... something is either red or not

I'm Confused still?

Experimental probability is what we infer from an experiment.

For example: if we toss a fair coin 100 times, head comes out 44 times. We say that head came out 44 times out of 100 (in this trial), and the experimental probability of head,
P(head)=44/100=0.44.
We can also say that the experimental probability of "Not Head" is
P(not head)=56/100=0.56
because 100-44=56 tosses were not head.
Alternatively, we can also say
P(not head)=100/100-44/100=1-0.44=0.56

To find the experimental probability of an event, you need to divide the number of successful outcomes (in this case, the number of times the spinner did not land on the color red) by the total number of outcomes (the total number of times the spinner was spun).

In this case, the table shows that the spinner was spun 50 times, and it landed on red 20 times. Therefore, the number of times the spinner did not land on red is 50 - 20 = 30.

To find the experimental probability of not landing on red, divide the number of times the spinner did not land on red (30) by the total number of spins (50):

P(not red) = 30/50 = 0.6

Therefore, the experimental probability of not landing on red, expressed as a decimal, is 0.6.

So, the correct answer is A. 0.6
