Which of the following figure has reflectional symmetry?
a. figure a
b. figure b
c. figure c
d. figure d

Step-by-step explanation:

Reflection symmetry refers to a symmetry with respect to an axis of reflection. Most common example is drawing an axis inside the figure, the resulting haves are like a mirror reflection.

So, in this case, if we draw a vertical axis on figure B, each half would be a reflection of each other. In other words, if we reflect figure B, it would result the same figure, because is symmetric.

Therefore, the right answer is option B.

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%
