- KINDLY ANSWER THE NUMBER 3. QUESTION ONLYWhat is the probability of not ever rolling a “seven” (when the spots of the two dice sum to 7) in 10 rolls of a pair of dice? a. .16b. .00c. .83d. None of the aboveChoose at random a young adult aged 19 to 22 years. Ask their age and where they live (with their parents, in their own place, or in some other place such as a college dormitory). Here is the probability model for the 12 possible answers: The next 3 problems use this probability model. Where do young people live? (a) Why is this a legitimate discrete probability model? (b) What is the probability that the person chosen is a 19-year-old who lives in his or her own place? (c) What is the probability that the person is 19 years old? (d) What is the probability that the person chosen lives in his or her own place? Where do young people live, continued. (a) List the outcomes that make up the event A = {the person chosen is either 19 years old or lives in his or her own place, or both} (b) What is P(A)? Explain carefully why P(A) is not the sum of the probabilities you found in parts (c) and (d) of the previous exercise. Where do young people live, continued. (a) What is the…

- For our study, we used the following formula: P (A or B) = P (A) + P (B) − P (A and B) (a) Is it ever possible that P (A) = 4.3? Explain why or why not. (b) What would need to be true about A and B to ensure that P (A and B) = 0? Justify your answer. Feel free to use an example probability question where you could define events A and B to help you answer the question.1Given the probability that "she's up all night 'til the sun" OR "she's up all night for good fun" is 0.42, the probability that "she's up all night for good fun" is 0.22, and the probability that "she's up all night 'til the sun" AND "she's up all night for good fun" is 0.28, what's the probability that "she's up all night 'til the sun"? Round to 2 decimal places as needed.
