Answer #1

The un ontains Pou ball s one is worth 4, tuo bnus are wos th , and on bal is worth 14 We random The random variable X dano

tan , 14+18+20 + 24 ← 12, 66チ NIN, Variance, 1441820 24 - 14, 149b 4 4 4 38 288 8 18 16 00 8 = 88-889

Therefore, the variance of X is 88.889.

  • Suppose we have two urns (a left urn and a right urn). The left urn contains N black balls and the right urn contains N red balls.

    Suppose we have two urns (a left urn and a right urn). The left urn contains N black balls and the right urn contains N red balls. Every time step you take one ball (chosen randomly) from each urn, swap the balls, and place them back in the urns. Let Xm be the number of black balls in the left urn after m time steps. Find the Markov chain model and find the unique stationary distribution when N=5
