Answer:

The probability is 4/45

Step-by-step explanation:

We know the chances of a blue marble is 4/10 so thats a first

The chances of a green marble WITHOUT the blue marble being put back is 2/9

So you multiply the two fractions

2/9*4/10

you’ll get 8/90 or simplified

4/45

How to find horizontal asymptotes with x as an exponent analytically?
tiny-mole [99]
When the base is greater than 1, the value approaches zero as the exponent goes to -∞. When the base is less than 1, the value approaches zero as the exponent goes to ∞. Whatever additions or factors you have that modify the exponential term will modify the asymptote accordingly.

When the three integers 400, 366, and 213 are divided by a positive integer d > 1, the remainders are the same. What is the l
raketka [301]

The number d is not a divisor of the integers 400, 366 and 213

The least possible value of d is 17

<h3>How to determine the least possible value of d</h3>

The numbers are given as:

400, 366 and 213

The divisor is given as: d

Where d > 1

To determine the least possible value of d, we make use of the following Python program, where comments are used to explain each action.

#This iterates from 2 to the smallest number of the three divisors

for d in range(2,213):

   #This checks for the common remainder

   if(400%d == 366%d) and (400%d == 213%d):

       #This prints the value of d, when the smallest remainder of all three integers is determined

       print(d)

At the end of the program, the output is 17

Hence, the least possible value of d is 17
