In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.

The formula to compute the combinations of k items from n is given by the formula:

Compute the number of ways to select four people as follows:

Compute the number of ways to selected two Democrats as follows:

Compute the number of ways to selected two Republicans as follows:

Then the probability  of selecting two Democrats and two Republicans as follows:

Thus, the probability  of selecting two Democrats and two Republicans is 0.4242.

answer: sine

step-by-step explanation:

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17
