In probability there is a very important distinction between the words AND & OR.

AND means that the outcome has to satisfy both conditions at the same time.

OR Means that the outcome has the satisfy one condition OR the other condition OR both at the same.

Answer:

$sec(x)$

Step-by-step explanation:

$cos(x)+cos(x)tan^2(x)$

Multiply cos(x) by 1:

$cos(x)*1+cos(x)tan^2(x)$

Factor out cos(x):

$cos(x)(tan^2(x)+1)$

Apply the pythagorean identity ( $tan^2(x)+1=sec^2(x)$ ):

$cos(x)sec^2(x)$

Rewrite $sec^2(x)$ :

$cos(x)(\frac{1}{cos(x)})^2 \\cos(x)\frac{1}{cos^2(x)}$

Cancel cos(x):

$\frac{1}{cos(x)}$

Rewrite:

$sec(x)$
