Emmanuel wants to buy a ticket to see his favorite basketball team during the upcoming season. The season includes 14 games in October, 13 games in November, 12 games in December, and 15 games in January. If he randomly is given one those games in those 4 months, what is the probability that the game will be in December?

22.22% game will be in December

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

14+13+12+15=54 games total

12 games in December

12/54=0.22222

22.22 possibility

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.
