There are 20 balls in the basker. from that 8 green,7 blue, 5 red balls.find the probability of select one ball from all the colors(not repitive the balls)4

• ((8C1)*(7c1)*(5c1))/(20c3)= 14/57

• 20 BaLL in basket Out of which we have to select 3 balls
  sample space = 20C3
  chance of selectinG one ball (8c1*7c1*5c2 )
  
  so ProbabliTY = (8c1*7c1*5c2 )/20c3
