<h2>The probability of first one to be blue isStep-by-step explanation:
In the given box, there are 4 red markers and 2 blue markers.
The given scenario will not affect the required probability as the selection of the second one is a case of future.
We need to find the probability of the first marker is blue.
The probability is .

Answer:
see attachments
Step-by-step explanation:
These are "one-step" equations.
To solve the ones involving addition or subtraction, identify the constant on the same side with the variable. Add its opposite to both sides.
To solve the ones involving multiplication or division, identify the coefficient of the variable. Multiply both sides by its reciprocal (or, equivalently, divide by that coefficient).
Here are more details for the problems on the first page.
- w +8 = -3 ⇒ w = -3 -8 = -11
- z +(-7) = -20 ⇒ z = -20 +7 = -13
- 1/5x = 11 ⇒ x = 5·11 = 55
- 1u = -88 ⇒ u = -88/11 = -8
- 1/9y = -2 ⇒ y = 9(-2) = -18
- 12 +n = 7 ⇒ n = 7 -12 = -5
- q +(-4) = 8 ⇒ q = 8 +4 = 12
