Answer:

<em>See the Venn diagram attached</em>

<u>Numbers given:</u>

  • <em>Total</em>: 100
  • Either a cat of a fish: 70
  • Cat: 46
  • Cat and fish: 16

<u>Neither a cat or a fish:</u> 100 - 70 = 30

<u>Fish:</u> 70 - (46 + 16) = 70 - 62 = 8

<u>Required probabilities are:</u>

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