Step-by-step explanation:
Using the definition of expected value, it is found that Ayo can be expected to make a profit of £55.8.
The <em>expected value</em> is given by the <u>sum of each outcome multiplied by it's respective probability.</u>
In this problem:
- The player wins $6, that is, Ayo loses £6, if he rolls a 6 and spins a 1, hence the probability is
.
- The player wins $3, that is, Ayo loses £3, if he rolls a 3 on at least one of the spinner or the dice, hence, considering three cases(both and either the spinner of the dice), the probability is

- In the other cases, Ayo wins £1.40, with
probability.
Hence, his expected profit for a single game is:

For 216 games, the expected value is:

Ayo can be expected to make a profit of £55.8.
