the two - way table shows the distribution of gender to favorite film genre for the senior class at mt. rose high school. which statement is true? the probability of randomly selecting a student who has a favorite genre of drama and is also female is about 17 percent. event f for female and event d for drama are independent events. the probability of randomly selecting a male student, given that his favorite genre is horror, is $\frac{16}{40}$. event m for male and event a for action are independent events. \n| |comedy|horror|drama|action|total| \n|---|---|---|---|---|---| \n|m|36|16|16|28|96| \n|f|54|22|24|44|144| \n|total|90|38|40|72|240|
Answer
Answer:
The probability of randomly selecting a student who has a favorite genre of drama and is also female is about 17 percent.
Explanation:
Step1: Calculate the probability
The number of female students who like drama is 24, and the total number of students is 240. The probability $P=\frac{24}{240}= 0.1 = 10%$. This statement is false.
Step2: Check independence for F and D
$P(F)=\frac{144}{240}=0.6$, $P(D)=\frac{40}{240}=\frac{1}{6}$, $P(F\cap D)=\frac{24}{240} = 0.1$. Since $P(F)\times P(D)=0.6\times\frac{1}{6}=0.1 = P(F\cap D)$, event F for female and event D for drama are independent events. This statement is true.
Step3: Calculate conditional - probability for male and horror
The number of male students who like horror is 16, and the number of students who like horror is 38. The probability of randomly selecting a male student, given that his favorite genre is horror, is $P=\frac{16}{38}=\frac{8}{19}\neq\frac{16}{40}$. This statement is false.
Step4: Check independence for M and A
$P(M)=\frac{96}{240}=0.4$, $P(A)=\frac{72}{240}=0.3$, $P(M\cap A)=\frac{28}{240}\approx0.117$. Since $P(M)\times P(A)=0.4\times0.3 = 0.12\neq0.117 = P(M\cap A)$, event M for male and event A for action are not independent events. This statement is false.
So the true statement is "Event F for female and event D for drama are independent events."
