Total number of bottles = 5 + 6 + 8 = 19 Let S be the sample space. Then, n(S) = number of ways of drawing 3 bottles out of 19 =19C3 = `(19 xx 18 xx 17)/ (3 xx 2 xx 1)` = 969 Let E = event of drawing e xactly two yellow bottles n(E) =6C2`xx` 13C1=`(6 xx 5)/(2 xx 1)` `xx` 13 = 195 `:.` P(E) = `(n(E))/(n(S))` = `195/969` = `65/323`
