A stock trader is deciding whether he should undergo a risky investment (high risk high reward). There is a 0.20 probability that he will undergo the risky investment and there is a 0.10 probability that he earns money given that he underwent a risky investment. Alternatively, there is a 0.80 probability that he loses money given that he went with a lower risk investment.a) What is the probability that he chooses a risky investment given that he already lost money from it?b) What is the probability that he chooses a risky investment given that he already gains money from it?c) What is the probability that he chooses a safe investment given that he already lost money from it?

The probability of the Dow Jones index rising on the first day of trading next week is thought to be 0.6. If it does rise then the probability that the value of shares in a publishing company will rise is 0.8. If the index does not rise then the publishing company’s shares will only have a 0.3 probability of rising. What is the probability that the publishing company’s shares will rise in value on the first day of trading next week?

The probability that a randomly chosen male has a blood circulation problem is 0.25. Subjects can either have a blood circulation problem (C) or not have a problem (CC). Males who have a circulation problem are twice as likely to be smokers as those who do not have a circulation problem. Subjects can either be a smoker (S) or be a non-smoker (SC). 1. What is the conditional probability that a male has a circulation problem, given that they are a smoker (that is P(C|S))?

You will take either a basket weaving class or a philosophy class, depending on what your advisor decides. You estimate that the probability of getting an A in basket weaving is 0.35 (it is a hard class), while in philosophy your probability of getting an A is 0.84. However, your major is straw construction, and the chance of your advisor choosing the philosophy class is only 40%. What is the probability that you get an A? The probability that you get an A is (Give the exact simplified probability.)
There is a 0.9985 probability that a randomly selected 30-year-old male lives through the year. A life insurance company charges $191 for insuring that the male will live through the year.
