Brilliant_brown [7]

Answer:

A = 100

B = 50

C = 30

Step-by-step explanation:

You can make this equation to solve:

2x+x+x-20=180

4x-20=180

+20 +20

4x=200

divide both sides by 4

200/4 = 50

x=50, B = x = 50

2x = 100 = A

x-20 = 30 = C

A bag contains tiles with the letters p -r-o-b-a-b-i-l-i-t-y Tyler chooses a tile without looking and doesn't replace it he choo

ipn [44]

Answer:

$\frac{1}{55}$

Step-by-step explanation:

Total number of tiles: 11 (obtained from counting the letters in probability)

Probability of picking the letter "i" the first time:

There are 2 letter "i's", and 11 total options, so the probability of picking an "i" is:

$\frac{2}{11}$

Probability of picking the letter "i" the second time:

We now have one less letter in the bag, as the first letter "i" was not replaced.

This means we now only have 1 letter "i", and 10 total options, so the probability of picking the last "i" is:

$\frac{1}{10}$

When you have two probabilities that are dependant on each other, you multiply them to get the probability of one, given that the other has happened.

Total probability:

$\frac{2}{11}*\frac{1}{10} = \frac{2}{110}$

Simplify by dividing by 2:

$\frac{1}{55}$
