Answer:those are your classes and the last one is the classes you completed i think im not really sure tho but yeah, umm byeee
Step-by-step explanation:
4+2+8+6 = 20 total
8 purple
so 8/20 reduced to 2/5 chance for a purple
then there will be 19 left
6 blue =
6/19 probability of having a blue one
2/5 * 6/16 = 12/80 reduces to 3/20 probability total
What do you mean "how many"? Like how many different rotations can you do and it'll be the same or just symmetries in general?
