a taste test asks people from Texas and California which pasta they prefer, brand A or brand B. this table shows the results
ELEN [110]

Answer:

D.

Step-by-step explanation:

Two events A and B are independent when

P(A|B)=P(A),

where P(A|B) is the probability that event A occurs given that event B has occured.

A = randomly selected person is from California

B = randomly selected person preferred brand A

A|B =  being a person from California and preferring brand A.

Hence,

P(A)=\dfrac{150}{275}=\dfrac{6}{11}\approx 0.55\\ \\P(B)=\dfrac{176}{275}=\dfrac{16}{25}=0.64\\ \\P(A|B)=\dfrac{96}{176}=\dfrac{6}{11}\approx 0.55

Since  P(A)=P(A|B), events are independent.
