James has organised a game to raise money for charity at a local fair. He rolls a fair six sided dice and flips a fair coin. If
Scorpion4ik [409]

The total amount that was raised for charity is £75.

<h3>What is the total amount raised?</h3>

Here is the sample space

                  1               2            3            4            5           6

Heads        1               4            9           16            25        36

Tails           1               8            27          64           125        216

Probability of getting a number greater than 30 = 4/12 = 1/3

1/3 x 450 = 150

Total value of people getting more than 30 : 150 x £1 = £150

Total amount paid = 50 x 450 = £225

Amount raised = £225 - 150 = £75
