What is the area of this triangle ?

A = 6 units ^2

Step-by-step explanation:

Let the base of the triangle be DE.  Its length is  3 units

Let the height of the triangle be from DE to point F.  That is 4 units  ( -3 to 1 is 4 units)

The area of the triangle is

A = 1/2 bh

  =1/2 (3)(4)

A = 6 units ^2

the answer is here: : )

:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
