Pot odds in poker refer to the ratio of the current size of the pot to the cost of a contemplated call. To calculate pot odds, you divide the size of the pot by the cost of the call. For example, if the pot is $100 and the cost of the call is $20, then the pot odds are 5-to-1.

Expected value (EV) in poker refers to the average amount of money that a player can expect to win or lose in the long run. To calculate EV, you multiply the probability of winning a hand by the amount you stand to win, and subtract the probability of losing a hand multiplied by the amount you stand to lose. For example, if you have a 50% chance of winning a hand that pays out $100, and a 50% chance of losing a hand that loses you $50, then your EV is (0.5 * $100) - (0.5 * $50) = $25.

It's important to note that the above explanation is a very simple explanation of the concepts and in real poker games and situations, the calculations and decisions can be much more complex and involve multiple other factors such as position, players behavior, and reading your opponents.
 
To calculate pot odds in poker, a player must compare the amount of chips they would need to call with the size of the pot. Expected value is then determined by comparing the pot odds to the odds of drawing a winning hand . If the odds of drawing a winning hand are better than the pot odds, it is considered a positive expected value play.
 
Pot Odds: Pot odds represent the relationship between the current size of the pot and the cost of a contemplated call. It helps you determine whether the potential payout justifies the risk.
To calculate pot odds, follow these steps:

Determine the current size of the pot.

Calculate the cost of your contemplated call.

Once you have these figures, you can calculate the pot odds by dividing the pot size by the cost of your call. The formula is:

Pot Odds = Pot Size / Cost of Call

For example, if the pot size is $100 and the cost of your call is $20, the pot odds would be 100/20, or 5:1.
