The table shows the results of spinning a four-colored spinner 50 times. Find the experimental probability and express it as a decimal
RED 20
BLUE 10
GREEN 9
YELLOW 11
what if it is p(not blue)
red=20/50 or .4
blue=10/50 or .2
green= 9/50 or .18
yellow=11/50.22
the results for each color over the total number of spins is the probability. to change it to a decimal divide the top number by the bottom number ex: 20 divided by 50.
I also left something out of the equation
what is p (not red)
p(not red) = 1 - p(red)
I still do not get it. can u walk me through this?
No clue don't know what you mean
To find the experimental probability of landing on each color when spinning the spinner, you need to divide the number of times each color appeared by the total number of spins.
In this case, the spinner was spun 50 times, so the total number of spins is 50.
Now, let's calculate the experimental probability for each color:
1. Red: The spinner landed on red 20 times. So, the experimental probability of landing on red is 20/50 = 0.4.
2. Blue: The spinner landed on blue 10 times. So, the experimental probability of landing on blue is 10/50 = 0.2.
3. Green: The spinner landed on green 9 times. So, the experimental probability of landing on green is 9/50 = 0.18.
4. Yellow: The spinner landed on yellow 11 times. So, the experimental probability of landing on yellow is 11/50 = 0.22.
Expressing these probabilities as decimals, we have:
Red: 0.4
Blue: 0.2
Green: 0.18
Yellow: 0.22
