Topic #3: Compound Probability 9. A letter from the word PENNSYLVANIA is chosen at random, then a standard die is rolled. Find
each probability.
a) P(L, then odd)
b) P(N, then less than 4) a) Pla vowel, then at least 3)

10. There are 8 red, 12 blue, 10 yellow, and 6 green marbles in a bag. A marble is chosen at random,
replaced, then another is chosen. Find each probability.
a) P(red, then green)
b) P(not red, then blue)
c) P(both yellow)

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.
