10%. However an electrician shouldn't be a master to have the necessary ability for common services. A master electrician is only required for highly technical issues.

If the events can be considered independent then the probability is (0.7)4 = 0.24 approx.

Using the Poisson approximation, the probability is 0.0418

If you select 45 cards without replacement from a regular deck of playing cards, the probability is 1. For a single randomly selected card, the probability is 2/13.
