Astandard deck of cards contains 52 cards. one card is selected from the deck. (a) compute the probability of randomly selecting aa clubclub or spadespade. (b) compute the probability of randomly selecting aa clubclub or spadespade or heartheart. (c) compute the probability of randomly selecting aa twotwo or diamonddiamond.

a) 1/2 = 50%

b) 3/4 = 75%

c)  1 / 52 or 1,9%

Step-by-step explanation:

In a standard deck of cards, there are 52 cards in total:

13 are hearts, 13 are diamonds, 13 are clubs and 13 are spades.

​(a) Compute the probability of randomly selecting a club or spade

How many cards are a club or a spade?

C = 13 clubs + 13 spades = 26 cards

Out of the 52 total, that means that:

P (club or spade) = 26/52 = 1/2 = 50%

​(b) Compute the probability of randomly selecting a club or spade or heart. ​

How many cards are a club or a spade?

C = 13 clubs + 13 spades  + 13 hearts = 39 cards

Out of the 52 total, that means that:

P (club or spade or heart) = 39/52 = 3/4 = 75%

(c) Compute the probability of randomly selecting a two or diamond.

There's only ONE two of diamond in  regular deck of cards, so...

P(2 of diamond) = 1 / 52 or 1,9%

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

41*67/2=1373.5
