Probability first one is blue is 4/6+4+4=4/14
the second one is also blue is 4-1/6+4+4-1=3/13

The probability of getting blue both time is 4/14*3/13=12/182=0.0659=6.59%

0.0659 or 6.59%

Mathematics

equation :

1. b + 5 = 3

2. 3b = - 6

3. 10b = -20

1. b = 3 - 5 = - 2

2. 3b/3 = - 6/3 = - 2

3. 10b / 10 = - 20 / 10 = - 2
