8.4 Option ‘Inverse Cumulative Probability’
Contrary to the previous option, this provides the value of the variable associated with a specific cumulative probability:
Be aware not to use the option Probability density to compute probabilities in a continuous distribution.
A machine produces 5% of defective parts. If packed in boxes of 100 units, calculate:
a) The probability that a box has exactly three defective units.
The number of defective units in a box is a random variable that follows a binomial distribution. The probability that this variable takes a certain value (3) is of interest now:
Calc > Probability Distributions > Binomial
b) The probability that a box has less than three defective units.
A packaging process specializes in filling containers. The weight of containers is normally distributed with a mean of 975 g and ...
