A heart is randomly chosen 7 out of 12 times from the cards below shown. Find the experimental probability of choosing a heart
There are 12 cards in total and 7 of them are hearts. The experimental probability of choosing a heart is the number of times a heart is actually chosen in the experiment divided by the total number of trials.
Let's say we perform the experiment 20 times and record the results. We might get something like this:
1. Heart
2. Not a heart
3. Not a heart
4. Heart
5. Heart
6. Not a heart
7. Heart
8. Not a heart
9. Not a heart
10. Heart
11. Not a heart
12. Not a heart
13. Heart
14. Not a heart
15. Heart
16. Not a heart
17. Heart
18. Not a heart
19. Heart
20. Not a heart
Out of 20 trials, there were 10 hearts chosen. So the experimental probability of choosing a heart is:
10/20 = 0.5 or 50%
So in this particular experiment, the experimental probability of choosing a heart was 50%. However, if we were to perform the experiment again with another set of 20 trials, our results may be different and the experimental probability may be slightly different.
