Only b is needed. lots of points. .

Ok so find the median so put the numbers in order so 82,83,84,85,85,86,86,86,87,87,88,89,90
then start from both sides cross off from both dies at the same time 
83,84,85,85,86,86,86,87,87,88,89

84,85,85,86,86,86,87,87,88

85,85,86,86,86,87,87

85,86,86,86,87

85,86,86,86

86,86 

so... 86 is the answer. i know its long but its the whole work hope it helped.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
