The Hundred markets use the event format and a defined scoring or settlement question. The Hundred counts an innings in 100 balls. Bowlers deliver blocks of five or ten consecutive balls and the fielding end changes after ten; use balls remaining rather than silently treating the format as a 20-over match.
Price describes a conditional return
Decimal odds include the original stake in the total return. In a hypothetical example, a 100-unit stake at 2.40 returns 240 units if the selection wins: 140 profit plus the original 100. A losing selection returns nothing under ordinary win-or-lose settlement. These figures illustrate arithmetic, not a forecast.
The reciprocal of decimal odds gives a price-implied probability before adjusting for margin: 1 ÷ 2.40 is about 41.67%. It is not a measured certainty about the event. When the implied probabilities of every mutually exclusive outcome add above 100%, the excess indicates an overround in that set of prices.
Compare prices only for the same event, selection and settlement conditions. An overall winner including extra play differs from a regulation-only result. A higher printed price can therefore concern a different proposition, while fees or exchange commission can also change the amount retained.
Match, Period and Player Markets
A market title specifies what will be measured. Match winner asks for an outcome; a total asks whether a measured quantity finishes above or below a line; a player market concerns a named participant. The same fixture can contain many questions with different winning conditions.
