speriamo non chieda le dimostrazioni delle altre distribuzioni ke non c'erano sul compito.. studiarle tutte è un casino...

UN dubbio! Ma quando chiedono la dimostrazione di una distribuzione, si intende la dimostrazione del teorema che determina il valore atteso, varianza e funz. gen. dei mom. di quella distribuzione???

Io credo di si, poi ci sono anche le approssimazioni con altre distribuzioni e ci sono i grafici delle funzioni (massa/densità di probabilità e di ripartizione).

vc bernoulli
vc binomiale
valore atteso

ragazzi per determinare la distribuzione di Dm come avete fatto??? Ho calcolato personalmente il suo valore atteso e poi la sua varianza. Ho verificato che E(Dm) = m(1-p) e var(Dm) = var(Sm) = mp(1-p). da questi due dati ho notato che DM ha una distribuzione binomiale.

Secondo voi è giusto come ragionamento???
