Now to find the mean deviation, we use the below formula:
Where:
represents the summation
X, represents the observation.
represents the mean
N represents the number of observation.
Therefore, the mean deviation is:
= 4
Answer:
-2/45
Step-by-step explanation:
-3/5 - (-5/9)
Subtracting a negative is like adding
-3/5 + 5/9
Get a common denominator of 45
-3/5*9/9 + 5/9 *5/5
-27/45 + 25/45
-2/45
What are you trying to find?
The correct answer is Choice D: 68%.
You have to make a tree diagram with all of the possibilities.
Here are the possibilities:
Rain - Win = 0.6 x 0.8 = 0.48
Rain - Loss = 0.6 x 0.2 = 0.12
No Rain - Win = 0.4 x 0.5 = 0.2
No Rain - Loss = 0.4 x 0.5 = 0.2
Adding up the two winning options gives us 68%
0.48 + 0.2 = 0.68
