What is Random Walks?
Here is my question:
The question is:
Suppose that you have £20 and need £50 for a bus ride home. Your only chance to get more money is by gambling in a casino. There is only one possible bet you can make at a casino: you must bet £10, and then a fair coin is flipped. If 'head' results you win £10 ( in other words you get your original 10 back plus an additional £10), and if it's 'tails,' you lose the £10 bet. The coin has exactly the same probability of coming up heads or tails:
What is the probability that you will get the £50 you need?
Thanks in advance guys!!

This question is;
A company needs to purchase a photocopier for the next three years. The present one it owns is worth £3000 but will lose £1000 in value in each of the next 3 years: after this it will be worthless and useless.
The beginning-of-the-year value of its yearly operating cost is £5000, with this amount expected to increase by £1000 in each subsequent year the copier is used.
A brand new copier can be purchased at the beginning of any year for a fixed costs of £7500. The lifetime of a new copier is 5 years and its value decreases by £1000 in its first year of use and then by £1500 in each of the following year. The operating cost of a new copier is £2500 in its first year, with an increase of £750 in each subsequent year.
I need to produce a cashflow for the beginning of year 1, year 2 and year 3. Help?
I have got for beginning of the year 1- 7,000, 3250,4000, -3500
