- bag contains 6 black and 8 white balls so total 14 balls, from the 14 balls we select one white ball so
probability to select one white ball= 8C1/14C1=8/14=4/7 - 10 years agoHelpfull: Yes(2) No(0)
- Total number of ball in the bag =8+6=14
Number of white ball in the bag=8
Then the probability of the drawn ball is white =8p1/14p1
=8/14
=4/7 - 4 years agoHelpfull: Yes(0) No(0)
