  the marked choice is correct

Step-by-step explanation:

The initial term is a1 = 100. The common ratio is r = 110/100 = 1.1. The generic term is ...

  an = a1·r^(n-1)

Filling in the known parameters, we find the sequence terms sn to be ...

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%
