A random survey of 131 high school students was conducted on April 25. The results are shown in the table. Let A = being male and B = have completed ALL DLD assignments for 5 weeks. Are the events independent? Explain.
P(A) = 0.42, P(B) = 0.62, P(A and B) = 0.26
P(A) x P(B) = 0.26 Since P(A) x P(B) = P(A and B), the events are independent.
P(A) = 0.42, P(B) = 0.62, P(A and B) = 0.26
P(A) x P(B) = 0.26 Since P(A) x P(B) = P(A and B), the events are not independent.
This cannot be determined since the number of males surveyed is not equal to the number of females surveyed.
P(A) = 0.42, P(B) = 0.62, P(A and B) = 0.26 and P(A or B) = 0.78 so the events are independent.
