PLEASEEE ANSWER A bag of jelly beans has 2 purple, 2 green and one orange. Saad pulls out
one and eats it before taking a second one to eat. What is the theoretical
probability that the two jelly beans are the same colour? *
2/10
4/10
2/20
3/20

m a t h w a y. c o m

step-by-step explanation:

answer: i think it is (1,-2)

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.

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate
