Susan rolled a die 888 times. Which of the following would be a good estimate of the number of times she rolled the number 3 on the die?

A. 248
B. 260
C. 151
D. 103

C. 151

Step-by-step explanation:

Since there are 6 sides on a die, and one of them is 3, the chance of rolling a 3 is 1/6.

To estimate how many times Susan rolled a 3, multiply 888 by 1/6:

888(1/6)

= 148

So, Susan rolled 3 on the die around 148 times.

This is closest to answer choice C. 151

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.
