The chart isn't for one specific game. Each fraction/column can represent a different type of game, and some are just to illustrate the concept. 1/2 = coin tosses and roulette (not counting 0 & 00 spots). 1/6 represents the toss of one 6-sided die.
1/4 can represent 2 coin tosses or two spins of the roulette wheel.
truncate = to cut off, (also rounding down) 166.88 becomes 166
For # of trials: Let's say I'm flipping a coin (the 1/2 column)
If I flip 1 time, I can expect it to land heads 50% of the # of flips I make: 100 flips, expect 50 heads
If I flip 2 coins at a time, one in each hand, I can expect heads to show up at least once 75% of the time: If I do a set of two flips 100 times, I could expect heads to show a least once in 75 of the pairs of flips.
Going all the way to the bottom; If I flip a single coin 7 times in a row I can be over 99.5% certain that heads will show at least once. So, If I did a 10,000 sets of ten flips each, I could expect heads to show before the 8th flip in 9,950 of those cases. "Before the 8th" could mean anywhere between the 1st all the way up to the 7th flip. That still leaves 50 cases where heads didn't show before the 8th flip.
The chart can't tell you which roll/throw/spin/flip something will happen in, but gives you a guideline of how far out you would have to go to get to a certain probability (not a guarantee) of a certain thing happening.
