7% of items in a shipment are known to be defective. if a sample of 5 items is randomly selected from this shipment, what is the probability that at least one defective item will be observed in this sample? round your result to 2 significant places after the decimal (for example, 0.86732 should be entered as 0.87).

0.30

Step-by-step explanation:

Binomial distribution formula :-

, where P(x) is the probability of getting success in x trials , n is the total number of trials and p is the probability of getting success in each trial.

Given : The probability that a shipment are known to be defective= 0.07

If a sample of 5 items is randomly selected from this shipment,then the probability that at least one defective item will be observed in this sample will be :-

Hence, the probability that at least one defective item will be observed in this sample =0.30

step-by-step explanation:

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
