QUICK PLEASE HELP THIS HOMEWORK IS DUE IN LESS THAN 10 MINUTES PLEASE AND THANK YOU A bag contains seven marbles. There are two orange marbles, four red marbles and 1 green marble. What is the theoretical probability of not grabbing a red marble?

3/7

Step-by-step explanation:

2+1=3 and there is 7 marble in all so it 3/7

tell me if im wrong

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

i think it is 18
