I need help asap. If you could answer both, I'd be grateful. I'll give a thumbs up, thanks. Only a brief explanation is needed.

About 1 in 1,100 people have le over 150. If a subject receives a score of greater than some specified amount, they are considered by the psychologist to have an IQ over 150. But the psychologist's test is not perfect. Although all individuals with IQ over 150 will definitely receive such a scorer individuals with IQs less than 150 can also receive such scores about 0.14% of the time due to lucky guessing. Given that a subject in the study is labeled as having an IQ over 150, what is the probability that they actually have an IQ below 150? Round your answer to five decimal places. Answer: 0.33333 Dengue-fever viruses are carried by mosquitoes. There are several different serotypes of the dengue virus, and one study showed that, of all mosquitoes that carried serotype A, a proportion of 0.16 also carried serotype B. If the proportion of serotypes A and B in the mosquito population are 0.4 and 0.73, respectively, what is the probability that a randomly selected mosquito carrying serotype B also carries serotype A? Round your answer to five decimal places. Answer: 0.08767
