A fish shop with odd pricing sells fish for the following prices: A trout costs $20, a salmon is $19, and a plaice comes in at $16. Using their pricing logic, how much would they charge for a mackerel?
$13. The price is calculated by using the position in the alphabet of the first letter of the name of the fish. An Albacore would be $1, a Bandfish would be $2. Note, I do not recommend using this pricing strategy unless you find yourself with an assortment of cheap Zebrafish.
The name ABRAHAM can be changed into a word for a primitive musical instrument by replacing each letter with a different letter. The repeated letters (A is this case) must be replaced with the same replacement letter in the new word.
Fred was almost done packing for the day, with five packages left. Unfortunately, Fred dropped the labels and had no idea which label went to which package. What is the probability that Fred managed to correctly label exactly four of the five packages?
Zero. If Fred had correctly labeled four packages, the fifth label would belong to the fifth package and all packages would be correctly labeled. Therefore it is impossible to mislabel exactly four packages.
