Question

A box contains 7 red, 6 white and 4 blue balls.If red ball is not taken

Answer 1

red = r1,r2,r3,r4,r5r6,r7.
white=w1,w2,w3,w4,w5 w6
blue = b1,b2,b3,b4
sample space = {r1,r2,r3,r4,r5,r6,r7,w1,w2,w3,w4,w5,w6,b1,b2,b3,b4} n(s) =17
let A be the event that red ball is not taken
A ={ w1,w2,w3,w4,w5,w6 ,b1,b2,n3,b4}
n(A)= 10...
