Answer: (a) Independent events , (b) 0.00075
Step-by-step explanation:
Since we have given that
Number of coins = 218
Number of rare Indian pennies = 6
Let Event A: When one of the 218 coins is randomly selected, it is one of the 6 Indian pennies.
Event B : When another one of the 218 coins is randomly selected (with replacement), it is also one of the 6 Indian pennies.
