If

inch is equal to 3 feet, then 1 inch = 6 feet because

and 3 * 2 = 6.
Thus 1 x 7 = 7, and 6 x 7 = 42.
42 feet.
Answer:
And solving we got:

So then for the problem given the probability that the entire bath will be accepted (none is defective among the 4) is 0.583
Step-by-step explanation:
For this case we can model the variable of interest with the hypergeometric distribution. And with the info given we can do this:
Where N is the population size, M is the number of success states in the population, n is the number of draws, k is the number of observed successes
And for this case we want to find the probability that none of the scales selected would be defective so we want to find this:

And using the probability mass function we got:
And solving we got:

So then for the problem given the probability that the entire bath will be accepted (none is defective among the 4) is 0.583
