1) 1/2 * 1/2 = 1/4
2) 43/100 of mine were heads, and (.43)^2 = .1849
3) 1/2 * 1/2 = 1/4
4)57/100 of mine were tails, and (.57)^2 = .3249
5) 1/2 * 1/2 * 2 (multiply by 2 because order doesn't matter) = 1/2
6) .43 *.57 = .2451
7) There is probably a difference becasue there wasn't enough data. The more times you flip the coin, the closer you'd get to 1/2 head 1/2 tails (theoretically), but you can't flip a coin an infinite amount of times, so it (usually) will not give you an exact 1:1 ratio between heads and tails
The probability of rolling 5 five on a dice would be 1/5
First week : -1.9 + 3.5 = 1.6
2nd week : -2.4
original water level had an increase of 1.6 inches
new water level has a decrease of -2.4 inches
