Odds Setup

Probabilistic reasoning

Add cards so the table meets the goal.

Starting level. Saved on this device.

Try 2 practice setups. Nothing is timed, and a hint follows each answer.
Then play 5 setups with no clock. The goals use more overlap as you get them right.

Tap a card in the tray to add it to the table, tap an added card to take it back, then press Submit.

How to play

Odds Setup practices reasoning about chances. Each card has a color and a shape, so one card can count toward both, like a red circle. The table already holds some cards. A goal says what chance you need, such as a red card as likely as a circle card. Add cards from the tray to meet it, then submit. Cards already on the table stay. There are five setups and no clock. Use Tab and Enter on the cards, or tap them.
