plz mark my answer as brainlist if you find it useful.
10/13 = 1% = 0.769230769
1%*100 = 100% 0.769230769*100 = 76.9230769 = 76.92
Answer:
E
Step-by-step explanation:
As you need a 47%, you universe of numbers should be form 0 to 99 (or 1 to 100, the important fact is you need 100 numbers). With this, you can discard A and D. You can also discard C, as you need 47 good realizations as you probability is 47%, and C gives you 48 (00 also counts)
You need as many observations as you can, to get a more consistent estimation. This means, as many observations as you can. You could use B or E, because both have 47 good observations (for u), but E gives you a larger sample.
If you are trying to get a head with 50% throwing a dime, you will, statistically, do better throwing it 47 times than only 10 times.
