The answer is 62/95. You determine this by calculating the probability of both students being girls.

Probability first student is girl: 12/20
Probability second student is girl: 11/19
Multiply 12/20 * 11/19 = 132/380 or 0.347
Probability of both students not being girls: 1 - 0.347 = 0.653 or 62/95

Pls help!!! if f(x) = 3x-2 and g(x) = 6-4x, fibd f(x) + g(x)

sp2606 [1]

So first off the equation we are solving is f(x) + g(x). So i want to plug in those equations first off. The new equation I get should be 3x-2 + 6 -4x. I then simplify this to -x+4 or 4-x.

Number c is really difficult

olya-2409 [2.1K]

Multiply each term in the equation by 4/1.
9-2y+2y+4=24

Combine like terms
13=24

Because the result is false, it is no solution.
