Answer: A.4/52
B.1/52
C.4/42
D.12/52
Step-by-step explanation:
A. Because there is 52 cards in a deck the answer will be out of 52. Since there is 4 aces in the whole deck the probability of player one getting all four aces is a 4/52.
B. Since there is 52 cards in a deck and only one ace of hearts it will be a probability of 1/52.
C. Since there are 52 cards in a deck the probability that they will hold an ace card is a 4/52 Bc there are four aces.
D. Because there are 52 cards in a deck, and 12 hearts in the deck in all they will have a chance of 12/52
You might need to simplify these fractions or convert to a percentage based on what your instructor wants.
Answer:
Step-by-step explanation:
1) f(x) = 7 - 8x²
f(3) = 7 - 8*3²
= 7 - 8*9
= 7 - 72
f(3) = -65
2) f(a) = -5(a-2)
f(3) = -5(3 -2) = -5 * 1 = -5
4) f(m) = m(m +4)
f(3) = 3*(3+4) = 3 * 7 = 21
I remember answering the same question, but you didn't attach any photos. But I remember that the answer is the first one.
I hope I helped. Stay safe and God bless!
