In a game of chance, a player has to spin a fair spinner. The spinner has 7 sections and an
arrow which has an equal chance of coming to rest over any of the 7 sections. The spinner
has 1 section labelled
R
, 2 sections labelled
B
, and 4 sections labelled
Y
(see diagram).
The player then has to throw one of three fair six-sided dice, coloured red, blue or yellow.
If the spinner comes to rest over
R
the red die is thrown, if the spinner comes to rest over
B
the blue die is thrown and if the spinner comes to rest over
Y
the yellow die is thrown.
The yellow die has one face with
on it, the blue die has two faces with
on it and the
red die has three faces with
on it. The player wins the game if the die thrown comes to
rest with a face showing
uppermost.

8 pears.
(i)
Find the probability that the total mass of 5 randomly chosen apples is more than
1600 grams.
[2]
(ii)
Find the probability that the total mass of 5 randomly chosen apples is more than
the total mass of 8 randomly chosen pears.
[3]
The recipe requires the apples and pears to be prepared by peeling them and removing
the cores. This process reduces the mass of each apple by 15% and the mass of each pear
by 10%.
(iii)
Find the probability that the total mass, after preparation, of 5 randomly chosen
apples and 8 randomly chosen pears is less than 2750 grams.
