Please answer A-D BUT use the other prompt in the first slide!!!! Thank you, this is a practice btw! So please show your work so I may understand In 1970, 98% of 30-year-olds in a country earned more than their parents did at age 30 (adjusted for inflation). In 2014, only 51% of 30-year-olds in the same country earned more than theirparents did at age 30. Complete parts a to d below.(a) What is the probability a randomly selected 30-yeat-old in 1970 earned more than his or her parents at age 30?The probability is(Round to four decimal places as needed.) (b) What is the probability that two randomly selected 30-year-olds in 1970 earned more than their parents at age 30?The probability is 0.7921.(Round to four decimal places as needed.)(c) What is the probability that out of ten randomly selected 30-year-olds in 1970, at least one did not earn more than his or her parents at age 30?The probability is 0.6882.(Round to four decimal places as needed.)(d) What is the probability that out of ten randomly selected 30-year-olds in 2014, at least'one did not earn more than his or her parents at age 30?The probability is 0.9998(Round to four decimal places as needed.)
