Answer:

P=\dfrac{1}{24}

Step-by-step explanation:

Let the names of 4 players start with letters A, B, C and D.

There is the the only chance that they shoot free throws in alphabetical​ order (ABCD).

Count how many different ways are to choose 4 letters from the hat. First letter can be chosen in 4 ways, the second letter can be chosen in 3 ways (only 3 letters left), the third letter can be chosen in 2 ways (only 2 letters left) and the fourth letter can be chosen in 1 way (the last letter left). So, there are

4\cdot 3\cdot 2\cdot 1=24

different orders.

The probability is

P=\dfrac{1}{24}

<em>the missing term is 5</em>

<em>12x² - 75 = </em>

<em>= 3(4x² - 25)</em>

<em><u>use formula</u></em><em> a² - b² = (a - b)(a + b)</em>

<em>= 3(2x - 5)(2x + 5)</em>

<em>= 3(2x + 5)(2x - 5) </em>
