40% in a fraction is 2/5 it is also 0.4 in a decimal if you're curious
The answer to this problem= 0
⇒6x + 2 + - 1 - 4x - 3 + - 2x + 2 = 0
⇒2 - 1 - 3 + 2 + 6x + -4x - 2x = 0
⇒1 - 3 + 2 + 6x + -4x - 2x = 0
⇒-2 + 2 + 6x + -4x + -2x = 0
⇒0 + 6x + -4x + -2x = 0
⇒6x - 4x - 2x = 0
⇒2x + -2x = 0
Combine like terms: 2x + -2x = 0
0 = 0
Solving
0 = 0

The color red can only appear 0,1 or 2 times. We also have that there are in total 9 outcomes. Hence, each event has the same probability, 1/9. Since the definition of probability is the number of favorable outcomes over the total number of outcomes, we get that since in 1 outcome we have both spins turning red, the probability of 2 times appearing red is 1/9. We also have 4 spins where there is only one red; rb, rg, gr, br. Hence, the probability is 4/9. Now, we have 4 outcomes where there is no red. Hence, the probability for 0 reds is also 4/9.
Succinctly P(0 reds)=4/9, P(1 red)=4/9, P(2 reds)= 1/9
