Chances are copied as printed in the box's table on the MM2 Wiki. When the table repeats one figure next to every item of a rarity (for example 70% beside each Common), those figures add up to more than 100%, so they describe the rarity as a whole, not each item.

Rainbow Box guide
The Rainbow Box has had three names. It began as the MLG Box, became the Chroma Box, and on August 6, 2016 the Rainbow Box replaced the Chroma Box after NikilisRBX tweeted a redesign idea for it. The wiki lists it as the only weapon box besides the holiday boxes that has no number in its name.
Very little of the older boxes survives in it. Shiny and Heat are the only items left from the Chroma Box, and Heat is the only item left from the MLG Box.
Contents
