Q:3 Two jars, A and B, hold 5 identical coins each, numbered from 0 to 9. Jar A contains even-numbered coins, while Jar B contains odd-numbered coins. One coin from each jars is randomly chosen simultaneously, without looking. The selected coins are combined to form a new number.

ii) If the rule is changed such that the coin from Jar B represents the tens place and the coin from Jar A represents the ones place, does the probability of getting a number greater than 50 increase/decrease?
iii) The coins from the Jars are re-distributed equally such that each jar has some even and some odd coins. Write a rule with the appropriate arrangement of coins in both the jars such that the probability of forming an odd number is higher on combining coins one from each jar.
