To calculate the number of different passwords possible, we need to consider the number of choices for each position in the password.

For each position, there are 5 choices since each letter can be either a vowel or a consonant.

Since the password consists of 5 letters, we multiply the number of choices for each position: 5 choices × 5 choices × 5 choices × 5 choices × 5 choices = 5^5 = 3125.

Therefore, there are 3,125 different passwords possible
