Which are the most and the least occurring digits ?

Answer

To determine the most and least occurring digits in the value of pi up to 50 decimal places, we can follow these steps:

### Step 1: Write down the digits of pi
The value of pi up to 50 decimal places is:
3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679821480865132823066470938446095505822317253594081284811174502841027019385211055596446229489549303819644288109756659334461284756482337867831652712019091456485669234603486104543266482133936072602491412737245870066063155881748815209209628292540917153643678925903600113305305488204665213841469519415116094330572703657595919530921861173819326117931051185480744623799627495673518857527248912279381830119491288314260769004224219022670167113900984882401283892260931036361976387803025516609911089798832701971652668631544878481660571979480979349113566791412400732157761862958688597285313585613714841455589350543360135769055141515366763379182059067348825304863302262995012741817312665409730717344409840935353922971437336404762280675022997907930528251951731632859203287372868283309068316106895607060527471254812270202904408594956681459816360303520179207789262447401663223440830461037336899636795048828125

### Step 2: Count the frequency of each digit (0-9)
We will count how many times each digit from 0 to 9 appears in the digits of pi.

- **0**: 2 times
- **1**: 5 times
- **2**: 5 times
- **3**: 8 times
- **4**: 5 times
- **5**: 5 times
- **6**: 4 times
- **7**: 4 times
- **8**: 5 times
- **9**: 8 times

### Step 3: Identify the most occurring digit
The most occurring digits are those with the highest frequency. From our counts:
- **3** and **9** occur 8 times each.

### Step 4: Identify the least occurring digit
The least occurring digit is the one with the lowest frequency. From our counts:
- **0** occurs 2 times, which is the least.

### Conclusion
- **Most occurring digits**: 3 and 9
- **Least occurring digit**: 0
