In a computer instant messaging​ survey, respondents were asked to choose the most fun way to​ flirt, and it found that ​P(D) =0
ikadub [295]

Answer:

P(Dᶜ )=0.41

Step-by-step explanation:

In the survey, the event D is the event of people who prefer to flirt directly in person.

Given that P(D)=0.590.

If someone is selected randomly, the probability that the individual prefers to flirt directly in person is 0.590.

If the person does not like to flirt in person, the probability of it will be the complement of event D.

From Probability Theory,

P(D)+P(Dᶜ )=1

0.590+P(Dᶜ )=1

P(Dᶜ )=1-0.590=0.41

The probability that the selected person does not like to flirt in person is 0.41.
