Answer:

<h2>1</h2>

Step-by-step explanation:

15 + 20 / 35

35/35 = 1 (certain)

The probability of choosing a female or senior is 1, because these are the only two groups represented in the class.

I'm always happy to help :)

<span>Simplifying 3x + 6 = 2x
  Reorder the terms: 6 + 3x = 2x
  Solving 6 + 3x = 2x
  Solving for variable 'x'.
  Move all terms containing x to the left, all other terms to the right.
  Add '-2x' to each side of the equation. 6 + 3x + -2x = 2x + -2x
  Combine like terms: 3x + -2x = 1x 6 + 1x = 2x + -2x
  Combine like terms: 2x + -2x = 0 6 + 1x = 0
  Add '-6' to each side of the equation.
6 + -6 + 1x = 0 + -6
 Combine like terms: 6 + -6 = 0
 0 + 1x = 0 + -6 1x = 0 + -6
Combine like terms: 0 + -6 = -6 1x = -6
 Divide each side by '1'. x = -6
 Simplifying x = -6
</span>so the answer is x =-6
