Question

Ramesh has a garments shop. He currently has 6 black, 4 red, 2 white and 3 blue shirts of same size in the stock. He picks 2 shirts randomly for the display. What is the probability that either both shirts are white or blue?"

Answer 1

Answer:

6 black 4 red 2 white 3 blue

Explanation:

p (e)=2+3/15

=5/15

=1/3

Answer 2

Answer:

white = 2/15

Blue = 1/15

Explanation:

s =(6+4+2+3)

n(s) = 15

White = n(e) =2

p(e)= n(e)/n(s) = 2/15

Blue = n(e) = 3

p(e) = n(e)/n(s) = 3/15 = 1/5
