Answer:
-5.5
Step-by-step explanation:
There are 26 - 10 = 16 girls. The number of ways to choose 2 girls from a set of 16 is C(16, 2) = 120. (Your class might be using a different notation for combinations, like
.)
The number of ways to choose 2 people (boys or girls) from a set of 26 is C(26, 2) = 325.
The probability of choosing 2 girls is 
Example: how to compute C(16,2):

Answer:
A. 3.6×10^5 grams
Step-by-step explanation:
Multiply the number of people by the amount per person:
(1.8×10^3)(2×10^2 g) = 3.6×10^5 g

The applicable rule of exponents is ...
(10^a)(10^b) = 10^(a+b).
