Help 6,7 ​

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
