Probability

In a box , there are 4 balls each tagged with a specified number 1 , 2 ,3 & 4.
In a random way , we get a ball without seeing it . We keep doing this as long as we get an odd number ? What's the community of elementary events.

You can pull out:
  1. An even number (2 events);
  2. An odd and then an even (4 events); or
  3. Two odds, and then an even (4 events).
A total of 10 events.
