a spinner used for a game is divided into sections: yellow, green, and orange. Janie spins the spinner 20 times. The spinner lands on green 8 times. What is the experimental probability that the spinner does not land on green?
it missed green 12 times. So,
P(~green) = 12/20
4/9
To find the experimental probability of the spinner not landing on green, we need to determine the number of times it didn't land on green out of the total number of spins.
First, we calculate the number of times the spinner didn't land on green by subtracting the number of times it did land on green from the total number of spins:
Number of times not landing on green = Total number of spins - Number of times landing on green
Total number of spins = 20 (given)
Number of times landing on green = 8 (given)
Number of times not landing on green = 20 - 8 = 12
Next, we use the number of times not landing on green and divide it by the total number of spins to find the experimental probability:
Experimental probability = Number of times not landing on green / Total number of spins
Experimental probability = 12 / 20 = 0.6
Therefore, the experimental probability that the spinner does not land on green is 0.6, or 60%.
