Draw two cards from a standard 52-card deck with replacement. Find the probability of getting at least one black card.

The value is  

Step-by-step explanation:

From the question we are told that

  The number of cards in a standard deck of cards is  n = 52

   The number of  black card in a standard deck of cards b = 26

    The number of  non-block cards in a standard deck of cards k =  26

Generally the probability of getting a black card is

=>      

Generally the probability of getting a non- black card is    

=>                  

Generally the sample space of the outcome of drawing two card from the  

standard deck of cards in such a way that at least one of the cards is a black card  is  

Generally the probability of obtaining at least on black card is mathematically represented as

=>      

=>      

f(x) is going down by 4
