    en.wikipedia.org/wiki/South_African_National_Lottery

    The National Lottery was introduced to South Africa on 11 March 2000. At the time it was run by Uthingo. [citation needed]After a marketing effort that aimed to reach 80 percent of South African homes directly [5] more than 800,000 tickets were sold in the first day of availability [6] Nearly R70 million worth of tickets were sold in the first three weeks of operation.

  4. Butadiene - Wikipedia

    en.wikipedia.org/wiki/Butadiene

    1,3-Butadiene (/ ˌ b juː t ə ˈ d aɪ iː n / ⓘ) [8] is the organic compound with the formula CH 2 =CH-CH=CH 2.It is a colorless gas that is easily condensed to a liquid. It is important industrially as a precursor to synthetic rubber. [9]

  5. Polybutadiene - Wikipedia

    en.wikipedia.org/wiki/Polybutadiene

    Polybutadiene forms by linking many 1,3-butadiene monomers to make a much longer polymer chain molecule. In terms of the connectivity of the polymer chain, butadiene can polymerize in three different ways, called cis, trans and vinyl. The cis and trans forms arise by connecting the butadiene molecules end-to-end, so-called 1,4-polymerisation.

    In this case, the expected utility of Lottery A is 14.4 (= .90(16) + .10(12)) and the expected utility of Lottery B is 14 (= .50(16) + .50(12)) [clarification needed], so the person would prefer Lottery A. Expected utility theory implies that the same utilities could be used to predict the person's behavior in all possible lotteries. If, for ...

  7. Sulfolene - Wikipedia

    en.wikipedia.org/wiki/Sulfolene

    3-sulfolene is mainly valued as a stand-in for butadiene. [3] [4] The in situ production and immediate consumption of 1,3-butadiene largely avoids contact with the diene, which is a gas at room temperature. One potential drawback, aside from expense, is that the evolved sulfur dioxide can cause side reactions with acid-sensitive substrates.

  8. 1,2-Butadiene - Wikipedia

    en.wikipedia.org/wiki/1,2-Butadiene

    1,2-Butadiene is the organic compound with the formula CH 2 =C=CHCH 3. It is an isomer of 1,3- butadiene , a common monomer used to make synthetic rubber. It is a colorless flammable gas, one of the simplest substituted allenes .

  9. Lottery wheeling - Wikipedia

    en.wikipedia.org/wiki/Lottery_wheeling

    Lottery wheeling (also known as a lottery system, lottery wheel, or lottery wheeling system) is a method of systematically selecting multiple lottery tickets to improve the odds of (or guarantee) a win. It is widely used by individual players and syndicates to secure wins provided they hit some of the drawn numbers.
