Answer 1

The answer is 1/30.

Explanation:

6 colored playing pieces: red, yellow, green, blue, purple, and white.

When you pick, the probability of picking yellow = no. of yellow / total no.

= 1/6

When your friend pick, only 5 pieces are left and the probability of picking blue = no. of blue / total no.

= 1/5

The probability that your friend picks the blue piece and you pick the yellow piece

= Probability of your friend picks the blue piece x Probability of ou pick the yellow piece

= 1/5 x 1/6

= 1/30

Answer 2

solution given:

totaln[S]=6for blue

n[B]=1

n[y]=1

now the probability that your friend picks the blue piece and you pick the yellow piece

=p[B]×p[y]=1/6×1/5 [one is removed]=1/30

so

1/30 is a required probability.
