Answer=25%

14 red marbles
12 yellow marbles
26 total marbles

To solve this, we need to first find out the probability of the individual events...

The odds of selecting a red marble is 14 out of 26 total marbles: 14/26

The odds of selecting a yellow marble after the first marble was NOT replaced is 12 out of 25. (25 since the first marble wasn't replaced: 26-1=25) 12/25

Now lets multiple both probabilities together to solve for the chance of both happening consecutively....

14/26*12/25= 168/650=84/325

84/325=<span>0.25846153846= 25%</span>

If the discriminat of a quadratic equation is 4 which statement describes the roots
Alex Ar [27]

Answer: using the discriminant to find the number of solutions to a quadratic equation b^2-4ac. positive discriminant indicates that the quadratic has <u>two distinct real number solutions.</u> The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.
