mhanifa

Answer:

  • 101 - min,
  • 5051 - max

Step-by-step explanation:

Minimum number of regions

You may have 100 parallel lines. This will give us 101 regions

Use following formula to find the maximum possible number of regions:

  • R(n) = 1 + n(n + 1)/2, where n is the number of lines
  • R(100) = 1 + 100*101/2 = 5051
