Answers:

P(A) = 7/12

P(B) = 1/2

=====================================================

Explanation:

To see how I calculated P(A), check out this link to this very similar question

brainly.com/question/27669586

--------------------

Now to calculate P(B)

If a number is divisible by 2, then the number is a multiple of 2.

In other words, the number is even.

Counting through the values in the table, you should find that there are 18 sums that are even (2, 4, 6, 8, 10 and 12). Refer to the dice chart below.

Here's a further breakdown

  • 1 copy of "2"
  • 3 copies of "4"
  • 5 copies of "6"
  • 5 copies of "8"
  • 3 copies of "10"
  • 1 copy of 12

Side note: We have nice symmetry going on.

There are 1+3+5+5+3+1 = 18 values total that are even numbers. The other half are odd numbers of course.

P(B) = 18/36 = (1*18)/(2*18) = 1/2

Alyssa's team won 5 out of every 7 games this season. If the team played 28 games this season, how many games did they win?
sladkih [1.3K]

Answer:

Alyssa's team won 20 games.

Step-by-step explanation:

We can introduce a variable that represents how many games Alyssa's team won.

Let x<em> </em>represent how many games Alyssa's team won.

We can now create a expression, we know that her team won 5 out of 7 games which would be equivalent to the fraction 5/7. We also know her team has played 28 games and five sevenths (5/7) of those they won.

This would give us the expression 5/7 = x/28.

We need to do this because 5/7 is equivalent to x the numbers of games they won over 28 the number of games they played.

Solving for  5/7 = x/28 we have:

5/7 = x/28  

We need to isolate x on the right side to do so we can multiply both sides by 28.

5/7 * 28 = x/28*28     simplifying

20 = x.

Therefore the number of games Alyssa's team won is 20 games.
