Mathematics
1 answer:
kozerog [31]3 years ago
7 0

Answer:

0.028

Step-by-step explanation:

The equation for opposite probabilities is 1 - P(A)

This means 1 minus the probability of event A which in this question is the event of the washing machine working properly.

So to find the chance that it will not work properly:

1 - 0.972 =0.028

I hope this helped!

A rating of good or excellent indicates the audience liked the movie, while a rating of poor indicates the audience disliked the movie.

<h3>How to determine the rating of the film from the 46–55 age group?</h3>

A movie producer accomplished a survey behind a preview screening of her latest movie to estimate how the film would be accepted by viewers from various age groups. The table displays the numbers of viewers in various age groups who ranked the film excellent, good, average, and poor.

25/446 = 0.05605

0.05605 * 100% = 5.605%

Out of the entire respondents, the percentage of respondents from the 46–55 age group who ranked the film excellent exists at 5.605%.
