testing him. One mummy is painted red on both sides. The other is red on one side and white on the other side. They randomly select a mummy,
and Plex can see only the top surface, which turns out to be red. What is the probability that the other side is red? If Plex is a gambler, should
he bet that the other side is red?

The probability that the other side is red is 2/3, which are good odds.

846. Mary was working in a chemistry lab with a mixture of chemicals that was 90
percent water and weighed 20 pounds (equal portions of water and the chemical mixture weigh the same). After returning to the lab from a weekend break,
Mary calculated the mixture which was now 50 percent water. How much does the mixture now weigh? (For purposed of this puzzle, assume the non-water
part of the mixture is not affected by evaporation).

4 pounds. The mixture was 90 percent water ( 18 pounds ) which meant 10 percent ( 2 pounds ) was not. Now it is 50 percent water and 50 percent solid; 50 percent of the weight is the 2 pounds of solid, which makes the whole mixture 4 pounds.

4
9
7
7
9
4
1 ?

9. The sequence reflects a single-digit sum of the digits of the squares of the first 9 counting numbers, obtained by adding the two digits together until a single digit results. 1 squared = 1 2 squared = 4 3 squared = 9 4 squared = 16 ( 1 + 6 = 7 ) 5 squared = 25 ( 2 + 5 = 7 ) 6 squared = 36 ( 3 + 6 = 9 ) 7 squared = 49 ( 4 + 9 = 13 ) ( 1 + 3 = 4 ) 8 squared = 64 ( 6 + 4 = 10 ) ( 1 + 0 = 1 ) 9 squared = 81 ( 8 + 1 = 9 ).

851. What common word contains the consonants l, k, n, w, and t and
the vowels i and e?

852. Insert +, -, and/or parentheses between the digits to make
126. No operator between two digits forms a multi-digit number (for example 3 4 becomes 34).

1 2 3 4 5 6 = 126

1 x 2 x 3 x 4 x 5 + 6 = 126.
