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 ) = \frac{13}{52} = \frac{1}{4}

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 ) = \frac{4}{52} = \frac{1}{13}

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 ) = \frac{1}{52}

Now,

P ( A ) * P ( B ) = \frac{1}{4} * \frac{1}{13}

P ( A ) * P ( B ) = \frac{1}{52}

Since,

P ( A ∩ B ) = P ( A ) * P ( B )

Hence,

2 events A and B are independent
