Question

If 21% of the customers in a restaurant order fish, what is the probability that the next 3 costumers in a row will order fish?

Answer 1

Probability of ordering a fish=21%=0.21, given that this is an independent event
then the probability of the next 3 customers in a row will order fish will be given by:
P(fish)=0.21×0.21×0.21=0.009261

Answer: 0.009261
