its just like the one we went through before

well the probability to draw a green marble is 4/10 in bag A and 3/5 in bag B. to find the answer, you just multiply those two fractions together ( 2/5 * 3/5 ) which is 6/25, so C hope this helps!

i know but i haven't took math in 4 years and now they give it to me on a computer program called grad point and i cant teach myself how to do all this over again. And so when i ask the teacher for help they tell me no and so i don't ever learn anything because i don't know how to do it.

thank you !

4/10 reduces to 2/5, that's why you multiply that by 3/5
