How did you come to your answers?

There are 23 total marbles in the bag, right? So as long as u don't permanently take out a marble (aka draw a purple marble and then don't put it back), ur answer will be over 23.

probability= (no. of favourable outcomes)/(no. of total outcomes)

anonymous · Answer

THen the numerator is the amount of things u want. So when u want purple marbles, and there are a total of 6 purple marbles, then u will have 6/23
