Answer:
9t + 8
Step-by-step explanation:
9t + (5+3)
Think of it like this. You have 9 oranges, 5 grapes, and 3 grapes. How many grapes and oranges do you have?
Math wise, we will have t representing oranges, and the normal numbers representing grapes. All you have to do is combine them using whatever sign separates them. If you need more help, let me know.
The empirical probability of a 4 or 5 is
(count of outcome = 4 or 5)/(count of all outcomes) = (44 +40)/240 = 7/20
The problem statement asks you to assume the outcomes will remain in this proportion going forward. That is, the number of outcomes (n) of 4 or 5 in the next 60 rolls of the number cube is expected to satisfy
7/20 = n/60
Multiplying that by 60 gives
n = 60*(7/20) = 21
Selection D is appropriate.
