6 from 49 Number Picker: How to use this preset
What the selection means
This format takes six distinct numbers from a single pool of 49. It works for a numbered activity board: the result identifies six cells to visit, discuss or complete. The same number cannot appear twice in one set; it may appear again in a later set.
Using the controls
Choose the number of sets and a tumble time, then press Pick Numbers. Each completed set contains six numbers. Selection order shows which ball emerged first; sorted order changes only the display. A new set refills the chamber, so numbers may return across sets.
An activity to try
Make a 7 × 7 grid and label its cells 1–49. Put a question, drawing prompt or movement in each cell. Run one set in PhysPicks and complete the six selected tasks. Agree before starting whether to follow selection order or work through the numbers in ascending order.

Choose the number range and how many numbers to pick, then adjust the mixing time to make a number-picking game for your activity.

These calculations assume uniform selection without replacement within each pool and independent chambers. They describe a mathematical model, not measured or certified probabilities for the PhysPicks physics simulation.
| Event defined before the selection | Theoretical probability |
|---|---|
| One specified main number is the first ball out | 1/49 ≈ 2.04% |
| One specified main number appears anywhere in the completed set | 6/49 ≈ 12.24% |
| Exactly one of your 6 preselected main numbers matches (secondary pool ignored) | 5,775,588/13,983,816 ≈ 41.3% |
| One specified complete combination, ignoring order | 1/13,983,816 |
C(49,6) = 13,983,816
For k picks from n numbers, a specified number is included with probability k/n. There are C(n,k) = n! / (k!(n−k)!) unordered sets. With two independent pools, multiply their combination counts. “One specified number appears” is different from “exactly one of my chosen numbers matches”. A previous result does not make a number due next time.
P(X = 1) = C(6,1) × C(43,5) / C(49,6)
