Answer:
Yes, the events are independent
Step-by-step explanation:
Two events are said to be independent when,
P ( A ∩ B ) = P ( A ) * P ( B )
Given,
One card is drawn from a pack of 52 cards
According to event A :
The card drawn is a spade
Number of spades in a pack of card = 13
Total number of cards = 52
P ( A ) = =
Similarly,
According to event B :
The card drawn is an ace
Number of spades in a pack of card = 4
Total number of cards = 52
P ( B ) = =
Now,
A ∩ B : The card drawn is an ace of spades
Number of an ace of spades in pack of card = 1
So,
P ( A ∩ B ) =
Now,
P ( A ) * P ( B ) = *
P ( A ) * P ( B ) =
Since,
P ( A ∩ B ) = P ( A ) * P ( B )
Hence,
2 events A and B are independent
