Solution

To solve this problem, we need to find the probability of drawing a card with a letter and then multiply it by the number of times the process is carried out.

Step 1: Find the total number of cards in the deck. This is the sum of the number of letter cards and number cards, which is 12 + 16 = 28 cards.

Step 2: Find the probability of drawing a card with a letter. This is the number of letter cards divided by the total number of cards, which is 12 / 28 = 0.42857.

Step 3: Multiply the probability of drawing a card with a letter by the number of times the process is carried out. This is 0.42857 * 14 = 6.

So, a reasonable prediction for the number of times a card with a letter should be drawn is approximately 6 times.
