In a recent survey, 75% of the community favored building a police substation in their neighborhhod. If 14...?

citizens are chosen, find the probability that exactly 8 of them favor the building of the police substation.|||BINOMIAL PROBABILITY





P = n!/[r! * (n - r)!] * p^r * (1 - p)^(n - r)





n = TRIALS [14]


r = SUCCESSES [8]


p = PROBABILITY OF SUCCESS [0.75] (75%)





P = 14!/[ 8! * (14 - 8)!] * (0.75)^8 * (1 - 0.75)^ (14 - 8) = 0.073 (7.3%) PROBABILITY 8 FAVOR POLICE STATION
