Answer: Option 'B' is correct.
Explanation:
Since we have given that
There is a coin and a deck of cards.
If there is a head, card is selected from the clubs and spades.
Number of clubs = 13
Number of spades = 13
If there is a tail, card is selected from the hearts and diamonds.
Number of hearts = 13
Number of diamonds = 13
Total size of the sample of this two stage experiment would be
13+13+13+13 = 52
Hence, Option 'B' is correct.
