output:
enter the number of urns : 3
enter the number of white balls to be drawn :2
for urn 1 enter its probability : 0.2

enter the number of white & black balls resp. : 7 3
for urn 2 enter its probability : 0.6

enter the number of white & black balls resp. : 4 6
for urn 3 enter its probability : 0.2

enter the number of white & black balls resp. : 2 8

the required probability is 0.177778
