Answer:
The probability that each player will receive three picture cards = 0.0324
Step-by-step explanation:
As given,
A deck of 52 cards contains 12 picture cards
Remaining card = 52 - 12 = 40
So,
Total number of ways in which 12 picture card is distributed =
Now,
The Total number of ways in which Remaining cards are distributed =
So,
Total number of ways of getting 3 picture card and remaining card = ×
=
Now,
Total number of ways to distribute 52 cards so that each people get 13 card =
∴ The probability =
= ×
= ×
= ×
= ×
= 0.0324
∴ we get
The probability that each player will receive three picture cards = 0.0324
