Answer 1

Answer:

See the Venn diagram attached

Numbers given:

• Total: 100
• Either a cat of a fish: 70
• Cat: 46
• Cat and fish: 16

Neither a cat or a fish: 100 - 70 = 30

Fish: 70 - (46 + 16) = 70 - 62 = 8

Required probabilities are:

• a) P(neither) = 30/100 = 0.3
• b) P(f) = (16 + 8)/100 = 0.24
• c) P(f not c) = 8/100 = 0.08
