A lolly bag contains 2 red, 3 green and 2 blue gum balls. What is the probability of selecting a green one?
A) 5/7
B)4/7
C)3/7
D)2/7

C

Step-by-step explanation:

Okay, first you would add up all the gumballs.

2+3+2=7

Now that will be the denominator.

Now for the numerator. You will check the question and find how man green gumballs there are. There are 3. So, now make it a fraction.

The answer choice is C.

Hope this helped!

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
