The number of people who survived the Titanic based on class and gender is in the following table. Suppose a person is picked at random from the survivors.
| Class | Female | Male | Total |
| 1st | 134 | 59 | 193 |
| 2nd | 93 | 25 | 118 |
| 3rd | 80 | 59 | 139 |
| Total | 307 | 143 | 450 |
a) What is the probability that a survivor was male?
Round final answer to 3 decimal places. b) What is the probability that a survivor was in the 1st class?
Round final answer to 3 decimal places. c) What is the probability that a survivor was a male given that the person was in 1st class?
Round final answer to 3 decimal places. d) What is the probability that a survivor was a male and in the 1st class?
Round final answer to 3 decimal places. e) What is the probability that a survivor was a male or in the 1st class?
Round final answer to 3 decimal places. f) Are the events "survivor is a male" and "survivor is in 1st class" mutually exclusive? Why or why not? Select an answer:
Yes because P(male and 1st class) = 0
No because P(male and 1st class) = 0
Yes because P(male and 1st class) is not equal to 0
No because P(male and 1st class) is not equal to 0
Yes because P(male or 1st class) = 0.
No because P(male or 1st class) = 0
Yes because P(male | 1st class) = P(male)
No because P(male | 1st class) is not equal to P(male)
Yes because P(male | 1st class) = P(1st class)
No because P(male | 1st class) is not equal to P(1st class) g) Are the events "survivor is a male" and "survivor is in 1st class" independent?
Why or why not? Select an answer:
Yes because P(male and 1st class) = 0
No because P(male and 1st class) = 0
Yes because P(male and 1st class) is not equal to 0
No because P(male and 1st class) is not equal to 0
Yes because P(male or 1st class) = 0.
No because P(male or 1st class) = 0
Yes because P(male | 1st class) = P(male)
No because P(male | 1st class) is not equal to P(male)
Yes because P(male | 1st class) = P(1st class)
No because P(male | 1st class) is not equal to P(1st class)
