With a typical 52-card deck that has 4 jacks, Margaret is playing a game. The game is initiated by the first player to choose a jack. When choosing first, Margaret's probability of selecting Jack is 1/13.
The same will occur since probability will be determined using the formula necessary outcome divided by total outcome.
Here, the total number of cards in the deck (total outcome) equals 52.
Given that Margaret can select any of the four jacks, the necessary result (number of jacks) is 4.
Probability is 4/52, or 1 by 13, which is the required probability for the question.

Answer: .3 or 3/10
Explanation: The probability that her first answer is correct is 2/5. Since she got the first guess correct, now there is only 1 correct answer out of 4. There is a 3/4 chance she will get the next problem wrong
So: 2/5 x 3/4 = .3
