Answer -
Given: The face cardsare removed from a full pack of 52.
By using the formula,
P (E) = favourableoutcomes / total possible outcomes
Four cards are drawnfrom the remaining 40 cards, so we have to find the probability that all ofthem belong to different suit.
Total possibleoutcomes of drawing four cards are┬а40C4
n (S) = ┬а40C4┬а=91390
Let E be the eventthat 4 cards belong to different suit.
n (E) =┬а10C110C110C110C1┬а=10000
P (E) = n (E) / n (S)
= 10000 / 91390
= 1000/9139
