Answer:
Then the probability that exactly 6 bridges in the sample are structurally deficient is 0.1063 or 10.63%
Step-by-step explanation:
Let X the random variable of interest "number of bridges in the sample are structurally deficient", on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
And we want to find this probability:
And if we use the probability mass function and we replace we got:
Then the probability that exactly 6 bridges in the sample are structurally deficient is 0.1063 or 10.63%
