Total number of cards = 52
i.e. Total number of outcomes = 52
There will be 4 sets of each card naming A, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K.
So, there will be a total of 24 cards between 3 and 10
Total number of favorable outcomes = 24
We know,
Probability of occurrence of an event = (Total number of favorable outcomes) / (Total number of outcomes)
Therefore, the probability of picking card between 3 and 10 = 24/52 = 6/13
