Answer:
1/32768
Step-by-step explanation:
We have 5 digit pin code plots and 8 choices per slot. Because repetition is allowed (1 digit can have 8 choices) so we multiply out the number of choices per slot
. Hence:
8*8*8*8*8 =
So there are 32768 different combination.
But correct guess on the first try is just only 1 time, so its' probability:
1/32768

The complete question is as follows:
Jessica is a custodian at Oracle Arena. She waxes 20
of the floor in
of and hour. At this rate, how many square meters can she wax per hour
?
Answer:
![\mathbf{\frac{100}{3}\approx33.33 \ m^{2} \ per \ hour}](https://tex.z-dn.net/?f=%5Cmathbf%7B%5Cfrac%7B100%7D%7B3%7D%5Capprox33.33%20%5C%20m%5E%7B2%7D%20%5C%20per%20%5C%20hour%7D)
Step-by-step explanation:
![\textrm{rate}=\frac{\textrm{Area waxed in square meter}}{\textrm{Time taken to wax in hours}}](https://tex.z-dn.net/?f=%5Ctextrm%7Brate%7D%3D%5Cfrac%7B%5Ctextrm%7BArea%20waxed%20in%20square%20meter%7D%7D%7B%5Ctextrm%7BTime%20taken%20to%20wax%20in%20hours%7D%7D)

Answer:
It's Same perimeter only
Step-by-step explanation:
It can't be the other two because they don't share the same area
