Step-by-step explanation:  

Probability is the chance of a certain event ocurring. For eg: We can find the 'probability' that a product is profitable.

Expectation, on the other hand, gives the average value of an experiment. For eg: To find the average profit that  person can achieve on the product, we use the term ' Expectation'.

Expectation is the weighted average.  

Example:  

If we throw an unbiased dice, then the probability of getting a number is 1/6.

But the expected value in this case is the weighted average ( value assigned times the probability) is

1*1/6 + 2*1/6 +3*1/6 +4*1/6 +5 *1/6 + 6*1/6 = 3.5.
