A) 0.3024

B) 0.4235

C) 0.6976

D) 0.8125

**Answer:** (C) 0.6976

**Solution:**

To find the probability that no two chocolate are identical = P(Y)

To find the probability that at least two chocolates are identical = P(x):**Formula:**

P(x) = 1 – P(Y)

__Calculation__

**No two chocolates identical:**

From 1^{st} bag = Probability = 10/10

From 2^{nd} bag = Probability = 9/10

From 3^{rd} bag = Probability = 8/10

From 4^{th} bag = Probability = 7/10

From 5^{th} bag = Probability = 6/10

P(Y) = 1(0×9×8×7×6)/(10×10×10×10×10)=0.3024

P(x) = 1 – P(Y) = 1 – 0.3024 = 0.6976
