18 bikes, 9 have gears (G), 11 have suspension (S) and 5 with both,What is the probability that a bike with suspension or gears?
vichka [17]

Answer:

  • 5/9

Step-by-step explanation:

  • Total number of bikes = 18
  • Bikes with gears S = 9
  • Bikes with suspension S = 11
  • Bikes with both GS = 5

<u>From the information above we have:</u>

  • Bikes with gears only = 9 - 5 = 4
  • Bikes with suspension only = 11 - 5 = 6

<u>Sum of the above two gives us the number of bikes with suspension or gears:</u>

  • 4 + 6 = 10

<u>Probability of selected bike be G or S is:</u>

  • P(G or S) = 10/18 = 5/9
