To calculate the experimental probability of getting one cube of each colour, we will need to keep track of the colours we choose for each trial. Here is an example of recording the colours for one trial:
Trial 1:
- First cube chosen: yellow
- Second cube chosen: red
- Third cube chosen: green
We can repeat this process for 19 more trials, recording the colours for each cube chosen. Once we have recorded all 60 cubes chosen (20 trials x 3 cubes per trial), we can count the number of times we chose one cube of each colour.
For example, let's say we recorded the following colours:
- Yellow, red, green
- Red, yellow, green
- Green, yellow, red
- Red, green, yellow
- Yellow, green, red
- Green, red, yellow
- Yellow, red, green
- Yellow, green, red
- Red, yellow, green
- Green, red, yellow
- Yellow, green, red
- Red, green, yellow
- Green, yellow, red
- Yellow, green, red
- Red, yellow, green
- Green, red, yellow
- Yellow, red, green
- Red, green, yellow
- Green, yellow, red
- Yellow, red, green
Out of these 20 trials, we have chosen one cube of each colour in 8 trials. Therefore, the experimental probability of getting one cube of each colour is:
P(one cube of each colour) = 8/20 = 0.4
So the experimental probability of getting one cube of each colour is 0.4, or 40%.
Do an experiment with two yellow cubes A red cube in a green cube. in the bag for you choose a cube you do not return the key before choosing the next cube choose three cubes all together to the experiment 20 times. what is the experimental probability of getting one cube of each colour
