Question

Rajani has 3necklaces and 3 pair of earrings, of blue, green and red stones. In what all different ways can she wear them? What is the probability of wearing the necklaces and the earrings of the same colour? Of different colours?

Answer 1

Answer:

1/3 of necklaces and 1/3 of earnings

Answer 2

NO OF NECKLACE=3

NO OF EARRINGS =3 PAIR OF BLUE= 6

.................................=3 PAIR OF RED=6

....................................=3 PAIR OF GREEN=6

SO ALL TOTAL= 21

SAME COLOR NECKLACE = 3/21=7 TIMES FOR NECKLACE

SAME COLOR OF EARRINGS AND NECKLACE BOTH = 21/21 =1 TIMES

OF DIFFERENT COLOR WILL BE =9/21=2.33.......
