1. Getting either all heads or all tails is a 1/1024 chance
2. Rolling a pair of dice and getting a sum of one has a chance of 0
3. Rolling a sum of 5 has a 2 in 21 chance
4. Rolling a sum of 12 has a 1 in 21 chance

£126

Step-by-step explanation:

Ratio is 2:1 so the difference between the amount of money will be "1".  This is equal to £42 so 2 x 42 is 84 and 1 x 42 is 42, add them together and the answer is £126.
