You want to know the probability of a blue marble.
Formula
P(blue) = #Blue / # Total
Givens
#Blue = 333
#Total = 333 + 444 + 555 = 1332
Solution
P(blue) = 333 / 1332 Divide by 111
P(blue) = 3/12
P(blue) = 1/4 or 0.25

oops sorry wrong question. sorry if I confused anyone :(
Answer:
x = -3 and y = -5
Step-by-step explanation:
2x - y = -1 ⇒ y = 2x + 1
Substitute this into 3x - 2y = 1 to solve for x:
3x - 2(2x + 1 ) = 1 ⇒ 3x - 4x - 2 = 1 ⇒ -x = 3 ⇒ x = -3
Now sub the value you found for x into y = 2x + 1 to find y:
y = 2(-3) + 1 = -5
So x = -3 and y = -5
