apologiabiology
so each event is indipentent of each other
chance=(desired outcomes)/(total possible outcomes)
3+4=7
7=total outcomes
3red
4yellow
so each time there is a 3/7 chance of drawing a red marble and a 4/7 chance of
red=3/7
yellow=4/7

so 3 yellow marbles and 1 red=4/7 times 4/7 times 4/7 times 3/7=(4^3 times 3)/(7^4)=192/2401 which is C

the answer is C 192/2401
