In a bag of apples there are 4 green apples and 2 red apples. bethany takes a green apple out of the bag and does not replace it. she then takes another apple out of the bag. what is the probability that the second apple is red?
a) 1/5
b) 1/6
c) 2/5
d) 2/6

Option C 2/5 is correct.

Explanation:

Total number of apples in the bag = 4+2=6

As stated, Bethany takes a green apple out of the bag and does not replace it. So, apples in the bag left are 6-1=5

Now, out of these 5 apples, she takes another apple out of the bag. Now, the probability that it would be a red apple is = (2 because there are 2 red apples)

Hence, 2/5 or 40% is the answer.

Probability of something can be defined as the amount of the entity to the total amount of entities.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
