The probability that he will pull out a nickel, then a quarter, then a nickel is 
<u>Explanation:</u>
Given:
Number of dimes = 3
Number of Quarters = 2
Number of pennies = 2
Number of Nickles = 5
Total coins = 3 + 2 + 2 + 5
= 12
Probability that Armando will pull out Nickel first =
After taking out Nickel, the total number of coins in the pocket will be 11
So,
Probability that he will pull a quarter = 
Total coins remaining = 11 - 1 = 10
Total Nickel remaining = 5 - 1 = 4
Probability that he will take our Nickel = 
Total probability =

Answer:
70 m^2
Step-by-step explanation:
The key shows that each square side on the grid measures 2 m. The base of the triangle measures 7 grid square sides, so it measures 14 m. The height of the triangle measures 5 grid square sides, so it measures 10 m.
area of triangle = bh/2
area = (14 m)(10 m)/2
area = 140 m^2/2
area = 70 m^2
