Question

A card is chosen at random from an ordinary deck of playing cards. what is the probability ,a diamond is chosen ,a king is chosen, a black 4 is chosen, a 7 of hearts is chosen

Answer 1

Answer:

Total probability = 52

A. Probability of diamond = 13/52 = 1/4

B. Prpbability of king = 4/52 = 2/26 = 1/13

C. Probability of a black 4 = 2/52 = 1/26

D. Probability of a 7 heart = 1/56

Step-by-step explanation:

Answer 2

Given; A card is chosen at random from an ordinary deck of playing cards, a diamond is chosen a king is chosen, a black 4 is chosen, a 7 of hearts is chosen

To Find;  the probability a diamond is chosen, a king is chosen, a black 4 is chosen, a 7 of hearts is chosen

Solution; A card is chosen at random from an ordinary deck of diamonds chosen, a king is chosen, a black 4 is chosen, a 7 of hearts is chosen

Probability=Number of favourable outcomes/Number of possible outcomes

Total number of cards = 52

Number of diamond cards = 13

probability of diamond card = 13/52 = 1/4

Number of kings =4

Probability of king chosen = 4/52 = 1/13

Number of 4 black = 2

Probability= 2/52 = 1/26

Number of 7 = 1

probability = 1/52

Hence the probabilities are 1/4 1/13 1/26 and 1/52
