hat fraction of mowers fails the functional performance test ? whar is the probability of having X failures in next 100 mowers tested
Inadequate data.
To determine the fraction of mowers that fail the functional performance test, you need to know the total number of mowers tested and the number of mowers that failed the test. The fraction can be calculated by dividing the number of failures by the total number of mowers tested.
To calculate the probability of having X failures in the next 100 mowers tested, you need to know the overall failure rate of the mowers. If you have this information, you can use the binomial distribution formula to calculate the probability.
The binomial distribution formula is:
P(X) = (n choose X) * p^X * (1 - p)^(n - X)
Where:
- P(X) is the probability of having X failures
- n is the total number of trials (in this case, 100 mowers tested)
- X is the number of failures
- p is the probability of a single mower failing the test
By substituting the appropriate values into the formula, you can calculate the probability of having a specific number of failures in the next 100 mowers tested.
