Suppose that two cards are randomly selected from a standard 52-card deck. (a) what is the probability that the first card is a spadespade and the second card is a spadespade if the sampling is done without replacement? (b) what is the probability that the first card is a spadespade and the second card is a spadespade if the sampling is done with replacement?

a.

b.

Step-by-step explanation:

We are given that two cards are drawn are randomly selected from a standard 52- cards deck.

Total cards=52

Total number of spade cards=13

Probability=

a.The probability of drawing two cards first card is spade and second card is spade without replacement =

The probability of drawing two cards first card is spade and second card is spade=

b. The probability of drawing two cards first is spade and second card is a spade with replacement =

The probability of drawing two cards first is spade and second card is a spade with replacement =

can you add an image ?

step-by-step explanation:

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
