Astandard deck of cards contains 52 cards. one card is selected from the deck. (a) compute the probability of randomly selecting a heart or diamond. (b) compute the probability of randomly selecting a heart or diamond or spade. (c) compute the probability of randomly selecting a ten or spade.

a) 0.5

b) 0.75

c) 0.307  

Step-by-step explanation:

We are given the following information in the question:

Number of cards in a deck = 52

Formula:

a) P(Heart or Diamond)

Total number of hearts and diamonds in a deck = 13 + 13 = 26

P( Heart or Diamond) =

b)  P(Heart or Diamond or Spade)

Total number of hearts, diamonds and spades in a deck = 13 + 13 + 13 = 39

P( Heart or Diamond or Spades) =

c)  P(10 or Spades)

Total number of spades in a deck = 13

Number of 10 in a deck = 4

P( 10 or Spades) =

111

step-by-step explanation:

the answer is 62.8 cubic units
