ANSWER:
The answer is 30.77%
STEP-BY-STEP EXPLANATION:
The probability would be the number of cards that meet the conditions divided by the total number of cards.
The pack of cards is a “Standard Pack", that is it has 4 suits (Diamonds, Hearts, Spades, Clubs), and cards Ace, 2 to 10 inclusive in each suit and Jack, Queen and King in each suit, giving a total of 52 cards.
There are 3 Face Cards in each suit (Jack, Queen, King)
Therefore there are 3 Face Cards in each suit in the pack or 3 x 4 (or 12) Face Cards in the pack.
Card 2, there is 4 times one for 4 suit.

Remember that the formula for simple interest is:
is the interest earned
is the principal amount invested
is the interest rate, represented as a decimal
is the amount of time in years
Using information the problem gave us, we can say that the amount of interest earned after one year is:
After 1 year, we will have earned $21. Remember though that we also need to find the amount we will earn after 4 months. Since there are 12 months in a full year, we can say that 4 mohts represents a third of a year. Thus, let's multiply our interest by one-third.
After 4 months, we will have generated $7 and after one year we will have generated $21.
