Document Summary
Answers to statistical questions given in probabilistic terms. Probability= always above > 0 - minimum & below < 1 - maximum. 2 dice 6 faces 6 faces = 36 outcomes. *so probability of rolling 7 or 11 with 2 dice = (cid:2876)(cid:2871)(cid:2874) = 0. 22. *probability involves possibilities / possible outcomes & depend on study: may be equally probable, may have different probabilities. Ex: roll of die = 1/6 or toss of a coin . *higher probability of ht/th - than other . *coin tosses 1st coin toss unrelated to 2nd coin toss. 6 6 for 2 independent events-rolls = 36 outcomes. Rule = number of possibilities = possible outcomes of event 1 possible outcomes of event 2 * and. 6 6 6 for 3 independent events-rolls [6 red 6 green 6 blue] = 216 possible outcomes. Definitions of probability: probability subjective definition, probability formal mathematical definition. # (cid:2925)(cid:2916) (cid:2900)(cid:2925)(cid:2929)(cid:2929)i(cid:2912)(cid:2922)(cid:2915) c(cid:2911)(cid:2929)(cid:2915)(cid:2929) or #(cid:2925)(cid:2916) (cid:2903)(cid:2931)(cid:2913)(cid:2913)(cid:2915)(cid:2929)(cid:2929)(cid:2916)(cid:2931)(cid:2922) (cid:2899)(cid:2931)(cid:2930)(cid:2913)(cid:2925)(cid:2923)(cid:2915)(cid:2929)
