Calculating Geometric Probability Abang side is scaring over a 100-acre area that
consists of thick forest and open fields, in the diagram
beow, the forested area is shaded in green and the open
sed is the white spade. Upon landing, the hang glider
reizes she has dropped her keys.
What is the probability that her keys have landed within
the forest?

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
