Answer 1

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 2

Answer:

Step-by-step explanation:

Theoretical odds of rolling an odd number is 4/8 = 50%

The experimental probability of rolling an odd number is 9/15 = 60 %

which is (60 - 50) / 50 = 20% more than the theoretical probability.

This is an imprecisely worded question as 60% is 10% more than 50%

but the number of actual odd numbers rolled is 20% more than was theoretically expected.  

Expected 7.5 odd numbers

1.20(7.5) = 9 actual odd numbers
