class Results extends React.Component {
  constructor(props) {
    super(props);

class GameOfChance extends React.Component {
  constructor(props) {

      counter: 1
    }
    this.handleClick = this.handleClick.bind(this);
  }
  handleClick() {
    this.setState({
      counter: this.state.counter + 1 // change code here
    });
  }
  render() {
    const expression = Math.random() >= 0.5 ? true : false
    return (
      <div>
        <button onClick={this.handleClick}>Play Again</button>
        { /* change code below this line */ }
        <Results fiftyFifty={expression} />
        { /* change code above this line */ }
        <p>{'Turn: ' + this.state.counter}</p>
      </div>
