Answer:
Step-by-step explanation:
Of the twenty times in this experiment the following are prime (3,5,2,7,3,7,2,2,7,3,3,5) or 12 of the twenty
12/20 = 6/10 = 60%
So 60% is the experimental probabilty.
The theoretical probability given that there are four prime numbers (2,3,5,7) out of 8 on the dice should be 50% because 1/2 of the numbers are prime.
The experimental probability is 10% more than the theoretical probability
60% - 50% = 10%
Answer:
A
Step-by-step explanation:
The expected profit would be the sum of all the possibility multiplied. It means,
<em>"We need to multiply the profit by its possibility and add it with the product of the loss and its possibility."</em>
<em />
This will be the expectation, or expected profit.
Let's do it:
Expected Profit =
