can't solve the problem and feel the description is vague

I'm not sure if I am doing right for assigning a value between 1 and 5.

app.js 
angular.module('foobar', [])
.controller("coolCtrl", function($scope) {
  $scope.helloWorld = function() {
    $scope.someNumber = 4;
  };
});

You have the right idea. But in your controller's callback function you do not need set a function expression to $scope.

angular.module('foobar', [])
  .controller('coolCtrl', function($scope){
    $scope.someNumber = 4
})

In addition to Jesse correct answer, Pay attention that somenumber will be available only for the current scope and it's children which will inherit the scope but will still have the option to overwrite the value of somenumber
