Total of 10 persons, out of which 6 are women. So probability of choosing the first woman = 6/10 probability of choosing the second woman = 5/9 probability of choosing the third woman = 4/8
Since we want all 3 steps to be a success, we need to have success in each of the steps, and the overall probability is given by the multiplication rule: P(all 3 are women)=6/10*5/9*4/8=120/720=1/6
If the two linear equations have the same slope, the equations represent the same line. Since a line intersects with itself everywhere, there will be an infinite number of solutions.
