HEL 2O POINT
If the first coin removed is blue, what is the probability of drawing a red coin after three red coins are put in the bag to replace the blue one? The probability of drawing a red coin after three red coins are put in the bag to replace the blue one that has been removed is

3/7

Step-by-step explanation:

9 blue coins and 3 red coins  were in the bag

We removed 1 blue coin

8 blue and 3 red

Now add 3 red coins

8 blue and 6 red coins = 14 coins

P ( red) = number of red coins / total coins

            = 6/ 14 = 3/7

its a little blurry tbh

step-by-step explanation:

think about it deeply and passionately about this property

i am sorry
