  13 1/3%

Step-by-step explanation:

The percentage change can be calculated from ...

  pct chg = ((new value)/(old value) -1) × 100%

  = (68/60 -1)×100% ≈ 13.33%

The change in Charles's height was about 13.3%.

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%
