In a computer instant messaging survey, respondents were asked to choose the most fun way to flirt, and it found that P(D)=0.560, where D is directly in person. Ifsomeone is randomly selected, what does P(D) represent, and what is its value?臺What does P(D) represent?A. P(D) is the probability of randomly selecting someone who chooses a direct in-person encounter as the most fun way to flirt.O B. P(D) is the probability of randomly selecting someone who did not participate in the survey.O C. P(D) is the probability of randomly selecting someone who did not have a preference in regards to the most fun way to flirt.O D. P(D) is the probability of randomly selecting someone who does not choose a direct in-person encounter as the most fun way to flirt.P (D) = 0.560 (Simplify your answer.)%3D

Mary is playing a game where she flips a coin with probability of head = p. She wins $1 if the coins comes up heads, and looses $1 if it comes out tails. She starts with $3, and p=0.6. What is the probability that Mary will become go broke? In this case, assume that N=infinity. That is, compute the probability she wins an amount of money N and then let N go to infinity. How does that help you compute the probability she goes broke? If she starts with 3 and all the money in play is N, we got a formula yesterday. Note that the numerator will be fixed and the denominator will depend on N Then let N go to infinity.

When randomly selecting adults, let M denote the event of randomly selecting a male and let B denote the event of randomly selecting someone with blue eyes. What does M|B represent? Is M|B the same as B|M ? What does M|B represent? A. The probability of getting someone with blue eyes, given that a male has been selected. B. The probability of getting a male or getting someone with blue eyes. C. The probability of getting a male, given that someone with blue eyes has been selected. D. The probability of getting a male and getting someone with blue eyes. Is M|B the same as B|M? A. Yes, because parenthesis B|M represents the probability of getting someone with blue eyes, given that a male has been selected. B. No, because B|M represents the probability of getting someone with blue eyes, given that a male has been selected. C. Yes, because B|M represents the probability of getting a male, given that…
