Answer:

Step-by-step explanation:
We have been given that Ross chose a card at random from a deck of 52 cards. Ross replaced the card and then chose a second card.
Let us find probability of getting a club.

Now let us find probability of getting the ace of spades.

Now let us multiply these to find probability of getting a club and ace of spades.
Therefore, probability of getting a club and then the ace of spades
.
Answer: The value of y is 3 units.
Step-by-step explanation:
Since we have given that
ABCD is a rectangle
So, their both diagonals are equal .
so, AC= BD
here,

So, According to question,

Hence, the value of y is 3 units.
