Hi,
Its been a couple years since I have done stats so I'm kind of rusty.
There is a bag of 6 balls. 3 are purple and 3 are green. What is the probability of getting at least 2 purple balls in 3 draws?
probability of getting 2 purple balls
3/6*2/5*3/4=0.15
probability of getting 3 purple balls
3/6+ 2/5+1/4=0.05
0.15+0.05=0.20
therefore, the probability of drawing at least 2 purple balls is 20%
*the question doesn't say, but I'm assuming that the balls are not being replaced
its that correct?
