wouldn't it be ratios, @NMVA ?

anonymous · Answer

thats strange, i wouldnt know why your school would be testing you on something you dont know, and @Poop_Emoji i like to use ratios in the same way as probability (finding the sample etc.)

you can draw a tree diagram for this 

|dw:1431546786481:dw|

because the 1st marble isn't replaced there is 1 less to select from for the 2nd marble. 

multiply the probabilities along the branches that match the outcome you need. 

then convert it to a percentage
