From Environment Canada: "Our experts on weather and climate have combed through 45 years of weather records, and determined the

probabilities based on the following criteria:
-a "white" Christmas is defined as having at least 2 cm of snow on the ground on December 25."
The probability that there will be a white Christmas in Vancouver is 11%.
The probability that there will be a white Christmas in Hamilton is 68%
What type of probability have they used to determine these probabilities?

A cup contains 3 blue paper clips,2 red paper clips,and 5 silver paper clips.what is the probability of not drawing a red paper
Elis [28]
Short Answer 0.8

Remark
The total number of possible draws is
3 Blue + 2 Red + 5 silver = 10
There are two ways of solving this, both of which will be used later on.

Method 1
If you don't draw a read paper clip, that means you will draw a silver or blue paper clip.
\frac{Silver + blue}{10} =  \frac{3 + 5}{10} =  \frac{8}{10} = \text{0.8}

Method Two
The other way is to draw a red one and take that probability away from 1. 
P(red) = \frac{2}{10} = \text{0.2}
1 - 0.2 = 0.8 Same answer.

Which shows the proper use of the distributive property
Karo-lina-s [1.5K]

Answer:

-2 (6x - y) = -12x + 2y

Step-by-step explanation:

By using the distributive property, you start by multiplying -2 and 6x which gets you -12x. You then multiply -2 and -y (in other words -y = -1y) so, -2* -y would get you 2 as a negative multiplied by a negative is a positive. So, adding them together would get your final answer: -2 (6x - y) = -12x + 2y
