Step-by-step explanation:
Total number of outcomes = 52 , since each deck consists of 52 cards
probability = Number of favorable outcomes/ Total number of outcomes
a) Number of favorable outcomes = Number of club cards = 13
P(club) =13/52 = 1/4
b) Number of favorable outcomes = Number of red cards = 26
P(red card) = 26/52 = 1/2
c) Number of favorable outcomes = Number of cards that are not hearts = 39/52 = 3/4
Answer:
3/10
Step-by-step explanation:
Answer: C
Step-by-step explanation:
We know that the answer is automatically C. What Kylie did was square each term. That is incorrect. Difference of squares is the entire factor squared, not each term. It is (x-1)(x+1) for example. Kylie did not understand this problem, nor did she solve it correctly. Therefore, C is the correct answer.
