Hi, could you please help me solve this

1. A gambler bets repeatedly on a standard (European-style) roulette wheel. Each time he/she bets $1 and gains an additional $1 with probability 18 19 The gambler 37 and loses his/her stake with probability 37 begins with $15 and bets repeatedly until he/she first reaches $20 (wins) or reaches $0 (loses.) Simulate 100 full runs of the gambler's games until he/she reaches either absorbing boundary. From these simulations, estimate: The probability that the gambler reaches $20 and not $0; ii ) The probability that the gambler places more than 50 bets before reaching either boundary; iii) The expected number of bets placed before reaching either boundary; iv) The expected number of times that the gambler has exactly $17 during each full game. Note: 100 full runs of the game requires simulation of 100 times that the player's money begins at $15 and ends at either $0 or $20, not just 100 bets
