Answer:
a) 74.5%
b) 84.3%
Step-by-step explanation:
a) If you were to refer to the glossary, as the problem statement suggests, it would tell you how to do this. Add up the scores and divide by the number of them.
Here, the 8 given scores have a total of 596%, so their mean is ...
596%/8 = 74.5%
Brandee might argue that this score <em>does not really represent her abilities</em>, because <em>her abilities were not demonstrated properly</em> on one of the tests.
__
b) Replacing the 0 score with 78% brings the total to 674%, so the new mean is ...
674%/8 = 84.3%
_____
<em>Additional comment</em>
Brandee's teacher might argue that the score <em>does</em> represent Brandee's abilities, because sometimes she fails to perform when needed.

<u>ANSWER: </u>
The probability that sum of numbers rolled is either 5 or 12 is
<u>SOLUTION: </u>
Given, Two dice are rolled.
We have to find what is the probability that the sum of numbers rolled is either 5 or 12
We know that, probability of an event =
Now, total outcomes for two dices = 6 for 1st dice x 6 for 2nd dice = 6 x 6 = 36.
Now, favourable outcomes = sum is 5 + sum is 12
= 4[(1,4), (2,3), (3, 2), (4, 1)] + 1[(6,6)]
= 5 total favourable outcomes.
Now, probability = 5/36
Hence, the probability that sum is either 5 or 12 is 5/36.
