Answer: 5%

Step-by-step explanation:

Probability for any event = \dfrac{\text{Number of favorable outcomes}}{\text{total outcomes}}

Given: Number of defective calculators = 25

Total calculators = 500

The probability that a calculator chosen at random will be defective= \dfrac{25}{500}

=0.05

=0.05\times100\%\\\\= 5\%

Hence, the required probability = 5%

The probability of one event given the known outcome of a (possibly) related event is known as _____ probability.
Deffense [45]

The probability of one event given the known outcome of a (possibly) related event is known as unconditional probability.

Given an incomplete sentence related to probability.

We are required to fill the sentence by the appropriate terms given as options.

Probability is basically the chance of happening an event among all the events possible.  It cannot be negative.

Marginal probability is basically the probability of an event irrespective of the outcome of another variable.

Conditional probability is basically probability of one event occuring in the presence of a second event.

Unconditional probability is basically the chance that a single outcome results among several possible outcomes.

Joint probability is a basically a statistical measure that calculates the likelihood of two events occurring together and at the same point in time.

From the above definitions and the sentence given we can say that the appropriate term is unconditional.

Hence the appropriate term which can be filled in the sentence is unconditional.
