5/9

Step-by-step explanation:

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

From the information above we have:

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

Sum of the above two gives us the number of bikes with suspension or gears:

4 + 6 = 10

Probability of selected bike be G or S is:

P(G or S) = 10/18 = 5/9
