6.  We have 18 flower bulbs, at first

 

So...if a customer buys 4 of them - one of each type - there are 14 left....and 2 lily bulbs remain

 

So...probability of a lily bulb on the next selection is just    2/14  =  1/7  ≈ 14%

 

 

6. Probability of R on the first draw  is  2/5

   Probability of R on the second draw  is  1/4

 

So....P(Two R's)  =    2/5  * 1/4 =     2/20   = 1/10
