Webb23 jan. 2024 · It is given that out of 300 students, 40 are selected randomly and asked whether they liked beef stew. Here, liking beef stew is a success and thirty-three percent of all students at a high school like beef stew. Success = p : Liking beef stew. Failure = q : Not liking beef stew . Probability of success is 33%. Probability of failure is WebbThe letter p denotes the probability of a success on one trial, and q denotes the probability of a failure on one trial. p+q =1 p + q = 1. The n trials are independent and are repeated using identical conditions. Because the n trials are independent, the outcome of one trial does not help in predicting the outcome of another trial.
