Answer:
Given
Bob has a box of 14 origami papers out of which 5 are red in colour, 6 are blue in colour and 3 are black in colour
Total papers = 14
To find atleast one black paper = 1- none
=1- selection of all papers except black
= 1- 11C1 /14C1
= 1- 11/14
=3/14
To find atleast one blue paper =1- none
=1- selection of all papers except blue
= 1- 8C1 /14C1
=1-8/14
= 6/14 = 3/7
In how many ways can he select the papers if he wants every selection to have at least 1 black paper and at least 1 blue
In how many ways can he select the papers if he wants every selection to have at least 1 black paper and at least 1 bluepaper = 3/14 x 3/7= 9/98
