## anonymous one year ago Alinn flipped a coin 20 times. The coin landed heads up 12 times and tails up 8 times. Part A: Based on the results, what is the experimental probability of the coin landing heads up? Show your work. (5 points) Part B: What is the theoretical probability of the coin landing heads up? Show your work. (5 points)

second part should be easy right? coin has two sides and is fair

3. anonymous

oh yeah part b im okay with c:

4. anonymous

what do you think that is as a probability ?

5. anonymous

for part b?

6. anonymous

first part is "relative frequency": favorable over total

7. anonymous

i only see A and B B is clearly $$\frac{1}{2}$$

8. anonymous

so for part a i put relative frequency

9. anonymous

12/20 is the "relative frequency"

10. anonymous

thats what i would put c:

11. anonymous

????????

12. anonymous

i would probably reduce the fraction

13. anonymous

$\frac{12}{20}=\frac{3}{5}$

14. anonymous

good idea
