Answer:
0.3597 = 35.97% probability that roommate A wins the game and thus does not have to wash the dishes.
Step-by-step explanation:
Independent events:
If two events are independent, the probability of both happening is the multiplication of their probabilities.
Rock-paper-scissors rules:
A player that choose rocks beats one who chooses scissors.
A player that choose paper beats one who chooses rocks.
A player that choose scissors beats one who chooses paper.
Probability that roommate A wins the game and thus does not have to wash the dishes.
3 possible events:
Roommate A - Rocks(21% of the time) and Roommate B - Scissors(18% of the time)
So

Roommate A - Paper(39% of the time) and Roommate B - Rocks(61% of the time).
So

Roommate A - Scissors(40% of the time) and Roommate B - Paper(21% of the time).
So

Probability of roommate A winning:

0.3597 = 35.97% probability that roommate A wins the game and thus does not have to wash the dishes.
Answer:
Trinomial
Step-by-step explanation:
we know that
A polynomial can be classified by its number of terms.
A polynomial with one term is called monomial, a polynomial with two terms is called a binomial, and a polynomial with three terms is called a trinomial
In this problem we have

This polynomial has three terms
therefore
Is a trinomial
Answer:
2100
Step-by-step explanation:
-3^2 = (-3)(-3) = 9 (because a negative times a negative is a positive)
Answer:
9a = 11a - 2a
9a = 9a
Step-by-step explanation:
9a = 11a - 2a
11 - 2 = 9
Similarly, 11a - 2a = 9a
Eleven minus two equals nine. Similarly, 11a minus 2a equals 9a. You can subtract them because they both have the same variable <u><em>a</em></u>.
