The probability is

#### Explanation:

If we denote the events as:

**jack** is chosen and

**spade** is chosen

Then the evemt we are looking for can be described as the alternative A **or** B (

The probability can be calculated using the formula:

Now we have to calculate the probabilities on the right side:

**and** a spade (a jack of spades).

Finally if we substitute calculated values we get:

This result can be simplified because both numerator and denominator can be divided by

So the answer can be written as:

**The probability is #4/13#**
