1. You have three standard decks of cards in front of you. What is the probability of drawing a heart card from all three decks? 2.12%
9.38%
1.56%
17.31%

1.56%

Step-by-step explanation:

A standard deck of cards has 52 cards, and 13 of these are hearts, as there are 4 suits, and 52/4=13. This means the probability of choosing a heart card from a deck of cards is 1/4, or 25%. Now to find the probability of doing this from 3 decks in a row, we simply cube 1/4 to get 1/64, and in percentage this is ~1.56%.

answer: the common difference is -0.10
