Check the picture below.

so let's find the lengths of those two sides in red, since are the length and width of the rectangle.

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

A boy has 380 prize tickets he wants to exchange for action figures at a prize booth. At
loris [4]

Answer:

Step-by-step explanation:

 

Hi there,

If the boy wants 80 small action figures

that is equivalent to 40 x 7 (as 7 tickets

gives him 2 small action figures)

= 280 tickets.

The 380 tickets he has originally minus the

280 leaves 100 tickets to get 20 large action figures

(100/5)

He will have 80 small and 20 large action figures

80:20 = 4:1

Hope this helps:-)
