Question

tara has two bags of marbles. the first bag contains 6 red marbles , 5 blue marbles and 4 green marbles tara will recomendly select one mararble what is the probality that tara will select a blue marble from each bag

Answer 1

well, in order to solve this we can put each marble into a fraction.

so for blue it would be 5 over 15 (5/15)

because there are 15 marbles in the bag but only 5 of them are blue!

but if you need a % then just divide the top by bottom

then you get a 33% chance of picking blue! hope this helps!
