Answer:

Yes, Based on this data, baldness and being over 45 are independent events, because P(bald | over 45) = P(bald).

Step-by-step explanation:

The given data is as following:

                Under 45   Over 45    Total

Bald         :   24                16           40

Not Bald  :    36               24          60

Total        :    60               40          100

<u>We should know that:</u>

The events A and B are independent when If P(A∩B) = P(A) * Pr(B)

Using conditional probabilities this property can be written as:

P(A|B) = P(A∩B)/P(B) = P(A) * Pr(B)/ P(B) = P(A)

So, we will check baldness and being over 45 independent events.

From the given data:

1. P(man is bald) = 40/100 = 0.4

3. P(bald | over 45) = 16/40 = 0.4

So, P(man is bald) = P(bald | over 45) = 0.4

<u>So, The events are independent. </u>
