Yes. Decision Making includes probabilistic reasoning: chance, expected outcomes and which option is better on average.
What is expected value?
The average result per go: multiply each outcome by its probability and add them up, then subtract any cost.
Do I need a formula sheet?
No. You need multiplication, fractions and counting outcomes, plus the on-screen calculator.

Probability and expected value in UCAT Decision Making.
Method
- Expected value: multiply each prize by its chance, add them, then take off the cost.
- Each wrong choice is a common slip: forgetting the cost, replacing a counter that was not replaced, or confusing the two directions of a test result.
