Mean first passage time python

Webthe first passage time occurs in time less than or equal to 2n−1. Clearly, p 2n−1 = ϕ 1 +ϕ 3 +···+ϕ 2n−1. In Table 1 we give some numerical values of p 2n−1. One sees that there is approximately a 7.8% chance that after 100 bets ones net earnings has never reached +1. Even after 10,000 bets there is approximately a 1% chance that
