]

const result = random.calculate(rates)
// {name: "R", rate: 60 }

> Make sure total rate is equal `100` percents

If you want to use more:

const rates = [
  { name: "R", rate: 60, other: any },
  {
    name: "SR",
    rate: 33.5,
    other: any,
  },
  ...
]

const result = random.calculate(rates)
// {name: "R", rate: 60, other: any }
