Answer: 21600 </h3>
==========================================================
Explanation:
There are 6 letters to pick from {A,B,C,D,E,F} and we have two slots to fill, where no repeats are allowed. This means we have 6*5 = 30 different ways to pick two letters.
There are 10 digits to pick from {0,1,2,...,9} and there are 3 slots to fill. This gives 10*9*8 = 720 different permutations for this portion.
Overall, we have 30*720 = 21600 different serial numbers possible.
Answer:
27%
Step-by-step explanation:
In the row Students ages 14-17 and column skip breakfast, there are 24 students.
In row total and column total, there 90 students.
24/90 are students age 14-17 who skip breakfast
24/90 = 12/45 = 0.26666667
Percent = decimal x 100
Percent = 0.26666667 x 100 = 26.666667
26.666667 is rounded to 27%
Hope this helps :)
