1. Let the current average be represented as

C = 85\%

.

2. Let the final exam score be represented as

F

, where the maximum is 100%.

3. The final exam counts as 20% of the final grade, and the rest of the coursework counts for 80%.

4. The overall grade can be calculated by:

\text{Overall Grade} = 0.80 \times C + 0.20 \times F

5. Substitute the current average into the equation:

\text{Overall Grade} = 0.80 \times 85 + 0.20 \times 100

6. Calculate the overall grade:

\text{Overall Grade} = 68 + 20

7. The best course grade your friend can earn is:

88\%

A box of numbered pens has 12 red, 12 blue, 12 green and 12 yellow pens. The pens for each colour are numbered from 1 to 12. There is a unique number on each pen, so no pen is exactly the same as any other pen in the box. When reaching into the box to randomly draw five pens without replacement, what is the proportion of getting exactly four pens of the same colour (Note: the numbers matter but the order does not)?
