The probability of getting ace of spade would be 1/52.

The probability of getting ace of spade would be 1/52. But in video it is mentioned P(ace) * P(spade).

Hey Ashutosh,

Thank you for your question!

I understand that the example given in the video is not completely intuitive. What is meant is the following:
P(ace of spades) = P(drawing an ace from the entire deck) * P(drawing a spade from all aces) = 4/52 * 1/4 = 1/52.

The argument could also be turned around such that:
P(ace of spades) = P(drawing a spade from the entire deck) * P(drawing an ace from all spades) = 13/52 * 1/13 = 1/52.

Hope this helps and keep up the good work!

Kind regards,

The question was asking about probability of drawing any Spades, not Ace of Spade. 

So, in playing cards, each suit has 13 cards , therfore, the probability for drawing any Spade = 13 / 52 which is 0.25
