A discrete random variable can only take the values 2,3,4 or 5. The probabilities associated with some of the outcomes are: P(X=2) = 0.2, P(X=3) = 0.3, P(X=5) = 0.1.
For a randomly drawn value of X, calculate P(X>3).

Nah, it’s definitely 0.5!

I think it’s 0.4, right?

Wait, what’s P(X=4)? Did we miss that?

Totally agree, it's 0.1 + P(X=4).

P(X>3) means we look at P(X=4) and P(X=5).

I practiced a similar question where we had to find probabilities for ranges. I think P(X>3) should be 0.4 based on what we know.

I think P(X>3) means we need to consider P(X=4) and P(X=5), but I can't recall what P(X=4) is.

I remember we calculated probabilities like this in class, but I'm not sure if I added them correctly.

Wait, does P(X>3) include P(X=3)? I thought it only counted values greater than 3.

Hmm, I'm a bit confused on the differences between para-virtualization and other virtualization techniques. I'll need to think this through carefully.

The APIC sounds familiar, but I can't recall if it's specifically for the COOP database. Did we cover that in class?

I'm feeling pretty confident about this one. Option B is the clear choice - using the Cloud Data Loss Prevention API to redact sensitive data before it's ingested into BigQuery.
