There are 700 shoppers.
151 + 201 = 352 were happy with the service received.
133 + 215 = 348 were not happy with the service received.
(a) A shopper was happy with the service received.
352 happy out of 700
p = 352/700 = 0.5029
(b) A shopper was unhappy with the service received.
348 unhappy out of 700
p = 348/700 = 0.4971
So 5 boys ,5 girls which means 5/10= 0.5
