To determine Find the probability that in a carton, there will be exactly 3 toasters that need repair. Explanation Calculation: It is given that in a carton a manufacturer ships 20 toasters. The estimated probability that one of the toasters will be sent for repair in each carton is 0.05. Properties of Bernoulli trials: In each trial there will be only two possible outcomes, success and failure. The probability of success for each trial is same. Each trial is independent to each other. 10% condition for Bernoulli trials: If the sample size is less than 10% of the population size, then is can be said that the Bernoulli trials must be independent. Binomial probability for Bernoulli trials: The number of successes in a specified number of Bernoulli trials is described by Binomial model. If the number of trials is n , with the probability of success is p and the probability of failure is q = 1 − p , and X be the event of the number of success in n independent trials, then the binomial probability model is defined as, P ( X = x ) = C n x p x q n − x , C n x = n ! x ! ( n − x ) ! and x = 0 , 1... n With mean is μ = n p and standard deviation is σ = n p q . It is denoted by X ∼ B i n o m ( n , p )
