In a contest each finalist must answer 5 questions correctly .each question is worth twice as much as the question before it. the fifth question is worth $1,600. how much is the first question worth a. $800 b.$400. c.$200. d. $100

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%

so, converting firstly the mixed fractions to improper fractions and then "adding".
