I believe these are the answers.
A
i) (y=5) x=6
ii) (y = -1) x=0
iii) (y = -2) x = -1
B
i) (x = -4) y = -5
ii) (x=2) y=1
iii) (x=5) y=4
Sorry if these are wrong but I hope the help.
Total customers: 26+42+33+24+40 =
165
The number of customers that bought 5-6 = 33
The probability would be 33/165
Total customers that bought fewer than 5 = 26+42 = 68
The probability is 68/165
