Each dice has a 1/6 chance to roll a six which means there are 6^5 possible rolls that 5 dice could have

if we isolate the roles that have a six, that means we are dividing the equation by 6

because only a 6th of them have a six, which brings it down to 6^4 possible roles

then we isolate the next six which would be the same thing because only a 6th of them have a six

so it would be 6^3 possible roles

next we need to turn 6^3 possible roles in to a fraction which involes divididing it from 6^5

which would be a 1/6^2 chance or 1/32 chance of roling a pair of sixes

I should mention the reason why I know this is because I was bored and wanted to know the

chances of getting a yatzee on the first roll (which is 1/6^4 by the way)

first things first, you need two equations

the two equations are 4x+12y=60 and x+y=6

then you want to simplify like dividing the first equation by 4

so it would be x+3y=15

now you want to subtract the other equation from it to get rid

of x so now it would be 0x+2y=9

then we simplify again so 2y/2=9/2

and it would be y=4.5

now we replace y with 4.5 in one of the equations (I did the second one

but you'll get the same answer if you do the first) so it would be x+4.5=6

than subtract 4.5 from both sides and your done and that leaves you with

1.5 hours runing and 4.5 hours biking

The formula for area is a*b=c where c is the area and a,b are the length and height

we know that 2a+2b= the perimeter of the shape and simplifying it would be

a+b=15

the best way to get your answer is to look at a graph

this graph shows the max it could be and the answer is easy to find because it is literally the middle of the line which is

(7.5,7.5) and that gives you an answer of 56.25
