The probability that evan purchases a comic book from the bookstore (event a) is 0.67, and the probability that glen purchases a comic book from the bookstore (event b) is 0.74. the probability that both evan and glen purchase a comic book is 0.2442. given this information, which statement is true?
a. events a and b are independent because p(a|b) ≠ p(a).
b. events a and b are independent because p(a and b) = p(a) × p(b).
c. events a and b are dependent because p(a and b) ≠ p(a) × p(b).
d. events a and b are dependent because p(a|b) = p(a).

Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Probability that Evan purchases a comic book from the bookstore (event A) =  0.67

Probability that Glen purchases a comic book from the bookstore (event B) = 0.74.

And,

Probability that both Evan and Glen purchase a comic book = 0.2442.

As we know that if two events i.e. A and B are independent then,

But here,

Therefore, the two events are dependent.

Hence, Option 'C' is correct.

yes. we do proportions in probabilities.

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)
