Answer:


Not independent
Explanation:
Given
See attachment for proper table
Solving (a): The missing probability
First, we add up the given probabilities


The total probability must add up to 1.
If the missing probability is x, then:

Collect like terms


Solving (b): P(High | Cancer)
This is calculated as:

So, we have:



Solving (c): P(Leukemia) independent of P(High Wiring)
From the attached table



If both events are independent, then:



Since the above is an inequality, then the events are not independent
