Someone had been collecting Pokemon cards, say 50 packs and found a table of species
as follows:
Copy #

Singles
46
Doubles

Triples
23
Quads
18
Quintuples

If he only has ‘1’ Charizard e.g. then the species Charizard would be tabulated in
‘Singles’ column, while if he has 4 Pikachu’s that would be an example to be put in
_____ column.
Based on this if he buys 10 more packs how many new species (characters) can he expect
to get?
Suppose a biologist traps butterflies for 2 years. E.g. he has trapped 118 species only
once, 74 species twice, etc. according to the table

If she spends one more year how many new species can she expect to catch?
Shakespeare has used 31,534 different words in his works. One attributes 884,687 total
words in his works. Suppose we think of each word as a species and make a table
capture

According to the table, how many words did Shakespeare only use one time? How many
did he use 6 times?
If we found an entire new ‘opus’ of Shakespeare with again 884,687 words how many
would be new? If we found a new poem of 429 words how many would we expect to be
new?

Summer Triangle
One of the signature star patterns of summer soars high overhead this evening: the
Summer Triangle. It's high in the east as darkness falls, and passes directly overhead
around midnight.
The brightest star in the triangle is Vega, in the constellation Lyra, the harp. Vega looks
so bright for a couple of reasons. First, it really is fairly bright -- it produces about 50
times more visible light than the Sun does. And second, it's one of our closest neighbors,
at a distance of just 25 light-years. That means the light we see from Vega tonight
actually left the star 25 years ago -- during Ronald Reagan's first term as president.
Well to the lower right of Vega, look for Altair, the brightest star in Aquila, the eagle. It's
even closer than Vega -- just 17 light-years. Altair is similar to Vega, though not as
bright. Both stars shine pure white.
The final member of the triangle is Deneb, to the lower left of Vega. It forms the "tail" of
the cross-shaped constellation Cygnus, the swan.
Deneb looks just about as bright as Altair. But if we could line up all three stars of the
Summer Triangle at the same distance from Earth, Deneb would blow the other two stars
away. It's a supergiant star that shines about 1700 times brighter than Vega. It shines
prominently in the night sky of Earth -- even thought it's 1500 light-years away.
