Final answer:
The probability of drawing a club or a diamond from a single draw of a well-shuffled standard deck of 52 cards is 50%, making the statement that it is 90% false. The correct option is B.
Step-by-step explanation:
The probability of selecting a club or a diamond from a well-shuffled standard deck of 52 playing cards is not 90%. A standard deck consists of four suits: clubs, diamonds, hearts, and spades, each with 13 cards. As clubs and diamonds together make up half the deck, the probability of pulling either a club or a diamond is calculated by summing the individual probabilities of drawing a club or a drawing a diamond:
P(Club or Diamond) = P(Club) + P(Diamond)
Since there are 13 cards of each suit:
P(Club) = 13/52 and P(Diamond) = 13/52
Therefore:
P(Club or Diamond) = 13/52 + 13/52 = 26/52 = 1/2 = 50%
This makes the statement that the probability is 90% false.
