Answer:
x=13
Step-by-step explanation:
9*2+8x-5=3x^2
9*2 = 18
18-5=13
13+8x=3x^2
3x^2 = 9x
13+8x=9x
-8x -9x
13=x
x=13
The final probability is the weighted average of the playing probabilities calculated over the possible weather options:
P(john practices cello; given that it rains) * P(it rains) +
P(john practices cello; given that it does not rain) * P(it does not rain) =
0.6 * 0.7 + 0.4 * 0.3 = 0.54
The probability is 54%

(60,1)
(120,2)
