<span>W = event where white marble is drawn
B = event where black marble is drawn
The two events W and B are independent. This is because the marble taken out on the first draw is put back into the bag. Since W and B are independent, we can use this rule
P(W and B) = P(w)*P(B)
Use the rule to get
P(W and B) = P(W)*P(B)
P(W and B) = (1/2)*(1/4)
P(W and B) = (1*1)/(2*4)
P(W and B) = 1/8
1/8 is equivalent to 0.125. Use long division or a calculator
0.125 = 12.5% </span>

The complete question in the attached figure
we know that
If two secant segments are drawn to a <span>circle </span>from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment.(Intersecting Secants Theorem)
5*(5+12)=6*(x+6)
5*17=6x+36
85=6x+36
6x=85-36
6x=49
x=49/6
x=8.17
the answer isx=8.17
