An extract from Buffon, [kiyoshiakima url]

"2 Simulation Programs
Buffon's Needle can be implemented easily on all but the smallest HP programmable …
2.2 BASIC
For the HP-71B the following BASIC program simulates the experiment. It prompts for the number of ten-throw trials, then prints the occurrences of each outcome and an estimate for π.
10 DESTROY ALL @ OPTION BASE 0 @ RADIANS @ DIM R(11) @ P=0
20 INPUT N @ FOR I=1 TO N
30 H=0 @ FOR J=1 TO 10 @ IF RND()<SIN(RND()*PI) THEN H=H+1
40 NEXT J @ R(H)=R(H)+1 @ P=P+H
50 NEXT I
60 FOR I=0 TO 10 @ PRINT I;R(I) @ NEXT I
70 PRINT 20*N/P"

BEST!
