Answer:
2x+20+3x+10 = 180 (int. angles, parallel)
5x+30 = 180
5x=150
x=30
Prob(first ball being blue) = 6 / (6 + 3 + 3) = 6/12 = 1/2
Prob ( picking a yellow ball) = 3 /12 = 1/4
As the 2 events are independent the probabilities are multiplied
So the answer is 1/2 * 1/4 = 1/8
Answer:
Step-by-step explanation:

Step-by-step explanation:
Because 3x+8 is not equal to 3x-5
3x cancel out for both side and +8 is not equal to -5
