Therefore, our second probability comes out to be 1/11. 3. Since the problem is asking for the probability of drawing two purple marbles, we need to multiply the two values together. (2/12) * (1/11) = 2/132 All we need to do now is simplify, and our answer is A. ...

Thankyou community of codeforces , I finally solved it! I solved it by finding the recurrence relation , say , a(n) is the probability, that sequence of length n has xor equal to 1 . Then ,a(n)=a(n−1)∗c+za(n)=a(n−1)∗c+z, wherec=2∗p1−1c=2∗p1−1z=1...
