42C+42A=2310
12A=420
A=35
we will find children ticket next
42c+30a=1890
30c+30a=1650

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.
