A box contains 10 green marbles and 11 white marbles. If the first marble chosen was a green marble, what is the probability of

Neko [114]

Answer:

11/20

Step-by-step explanation:

At the beginning, the number of marbles in the box are:

10 green marbles

11 white marbles

The first marble chosen is green, and then it is not replaced in the box. Therefore, the number of green marbles left in the box is 9.

Therefore, the total number of marbles left in the box is:

$n=9+11=20$

Now we want to find the probability to choose a white marble. The number of white marble is

$w=11$

Therefore, the probability of choosing a white marble is:

$p(w)=\frac{w}{n}=\frac{11}{20}$

Ganezh [65]

She would need to make an 89 on her last test. I hope this helped ^^

What I did is I put a made a list in ascending order (Least to greatest). Next, I added a number starting from 80 and then counted up. I added every number together and divided it by 5 every time I changed the number. Finally I got to the number 89 and it totaled to be 85.
