(1) What is the probability that of the 20 randomly selected cars, 19 or more cars will be a color other than red?

Answer 1

solution <5) Lis Binomial ♡ Bimonial © Not Bimonial, Because in binomial only two outcomes are possible Success or failure @ Not Bimonial Because, Population size is small and Experiment is not performed with replacement @ blRed) = 0.08 M -20 xn Bimonial P(x=4) = (m) be qm-se - 120) (0.08)*(0.9930-4 - 10.0523) (1) P(19 or more other colour) = P (one or less red) =) P(x = 1) = P(x=0) + P(x=1). - (20) 6.083(0.92) + (?)(0-089 (0.92) = 0.51 69 20 19
