Answer.      [A]
Solution. Probability: probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Total number of cases = 52
Red face cards = 6
Favorable cases = 6
Let event A is to select a card from 52 card.
Probability that it is a red card is p(A)
P\left ( A \right )= \frac{Number\, of\, favourable\, cases}{Total\, number\, of\, cases}
P\left ( A \right )=\frac{6}{52}= \frac{3}{26}
