Answer
Probability of card being greater than 3 and less than 7 = $\frac{3}{13}$
Work Step by Step
Total number of outcomes when dealing a card from card deck = 52
Total number of favorable outcomes when dealt card is greater than 3 and less than 7 = 12
(4 cards - four number 4 cards - five number, 4 cards - six number)
When a card is dealt from 52 cards the probability of card being greater than 3 and less than 7 = $\frac{12}{52}$
= $\frac{3}{13}$
