How many 7s are there total? 4
So 4/52 of the cards are 7s.
Probability of getting a 7 first is 4/52
second time is 3/51
third time is 2/50
fourth time is 1/49
(4/52) * (3/51) * (2/50) * (1/49)
Multiply them together to get: 3.69378521 × 10^-6
What is the probability of drawing 4 sevens in succession from 52 playing cards given cards are not replaced?
3 / (51 x 49 x 25 x 13)
