A widget company produces 25 widgets a day,5 of which are defective.Find the probability of selecting 5 widgets from the 25 prod
MariettaO [177]

Answer:

0.292

Step-by-step explanation:

Combinations can be used to solve the following problem.

We are choosing 5 widgets from 25 = ²⁵C₅

We want to select zero widgets from defective widgets = ⁵C₀

From the 20 non-defective widgets we want to select 5 = ²⁰C₅

So the probability is:

P = ( ⁵C₀ * ²⁰C₅) / ²⁰C₅

P = (1 * 15504) / 53130

= 15504/ 53130

=0.292 ..

Honor Roll: Curfew 18 No Curfew 10 No Honor Roll: Curfew 2 No curfew 7
Rudik [331]

Among the students who did not make the honor roll. Then the relative frequency of having no curfew will be 7.

<h3>How to find the relative frequency?</h3>

Relative frequency is the ratio of the considered sub-group count to the total count. (so its frequency of the considered sub-group relative to the total frequency).

                                     Curfew                 No Curfew No

Honor Roll:                       18                                10

No Honor Roll:                 2                                  7

Among the students who did not make the honor roll.

Then the relative frequency of having no curfew will be 7.
