Hello!

We have two probabilities we can use; we have 170/400, for our experiment, and 1/2, which is our theoretical probability.

To solve, we just multiply the two probabilities.

$\frac{170}{400}(1/2)$ =0.2125≈21.3

Therefore, we have about a 21.3% chance of this event occurring.

I hope this helps!
