Answer:

Since $P(A \cap B) = P(A) \times P(B)$ , the events of getting at least one text from Pedro and at least one text from Max are independent.

Step-by-step explanation:

Two events, A and B, area independent if:

$P(A \cap B) = P(A) \times P(B)$

In this question:

Event A: getting at least one text from Pedro.

Event B: getting at least one text from Max.

Jackson has received at least one text from Pedro on 45 of the last 50 days:

This means that $P(A) = \frac{45}{50} = 0.9$ .

Jackson has received at least one text from Max on 40 of the last 50 days:

This means that $P(B) = \frac{40}{50} = 0.8$

Jackson has received at least one text from both Pedro and Max on 36 of the last 50 days.

This means that $P(A \cap B) = \frac{36}{50} = 0.72$

Verify dependency:

We have that $P(A \cap B) = 0.72$ .

$P(A) \times P(B) = 0.9 \times 0.8 = 0.72$

Since $P(A \cap B) = P(A) \times P(B)$ , the events of getting at least one text from Pedro and at least one text from Max are independent.
