Answer:
(0.5,3)
Step-by-step explanation:
In a bag, there are 10 black plastic chips, 7 yellow, 5 red, and 3 green.
Total number of chips = 10+ 7 + 5 + 3 = 25
Probability = 
Probability ( back drawn) = 
Two chips are drawn at random with replacement.. So black is replaced
Probability ( red drawn) = 
Probability (black, then red) =
* 
=
= 
Y = x + 1
y = 1/2x + 3
x + 1 = 1/2x + 3
x - 1/2x = 3 - 1
1/2x = 2
x = 2 / (1/2)
x = 2 * 2/1
x = 4
y = x + 1
y = 4 + 1
y = 5
so ur solution is : (4,5)
