Ответ:
False
Step-by-step explanation:
Given experiment:
A coin is flipped 20 times.
The results are 12 heads and 8 tails.
Statement: The theoretical probability of getting heads is 60%.
To tell true or false.
Solution:
For the given experiment the results is 12 heads and 8 tails for a coin flipped 20 times.
The experimental probability of getting head can be given as:
⇒![\frac{12}{20}\times 100](/tpl/images/0453/4707/3f95f.png)
⇒![0.6\times 100](/tpl/images/0453/4707/e2b42.png)
⇒![60%](/tpl/images/0453/4707/a1487.png)
while the theoretical probability of getting heads can be given as:
⇒
[Since probability getting heads on one flip is 0.5]
⇒![50%](/tpl/images/0453/4707/2d83d.png)
Thus, the statement is false.

✅ FALSE
✧・゚: *✧・゚:* Explanation: *:・゚✧*:・゚✧
❗ This is Experimental Probability: 12 Heads out of 20 Tosses.
12/20 reduces to 6/10, 0.60, and 60%.
The answer to this question is FALSE, because this is NOT Theoretical Probability.
