Answer:
a. 0.6
b. 0.5
Step-by-step explanation:
Let A be the event that student takes algebra and C be the event that student takes Calculus 3.
P(A)=0.60
P(C)=0.5
P(A and C)=0.30
a.
We have to find P(A/C).
P(A/C)=P(A and C)/P(C)=0.3/0.5=0.6
Thus, if someone took Calculus 3, the probability that he/she took Linear Algebra too is 0.6 or 60%
b.
We have to find P(C/A)
P(C/A)=P(A and C)/P(A)=0.3/0.6=0.5
Thus, if someone took Linear Algebra, the probability that he/she took Calculus 3 too is 0.5 or 50%
In one apple there are 80 calories
Answer:
Step-by-step explanation:
a) Out of 5, 1 only one is wrong. So number of questions answered correctly is (4/5)
To find the percentage, multiply (4/5) by 100
b) It is not possible to find the actual score because we don't know how many questions were there actually and the score for each question.
1/3 divided by 6 is 1/18. So each plant gets 1/18 quarts of liquid plant fertilizer.
Answer:
64 different black jack hands
Step-by-step explanation:
there are 4 aces in a deck, and you can score a blackjack if any of these 4 aces is paired with any of the 16 different cards that are worth 10 points. Total number of different blackjack combinations = 4 aces x 16 different tens = 64.
Even though the number of possible blackjack hands might seem large, the possibilities of actually getting one are really low:
possibility of getting 1 ace = 4/52 = 1/13
possibility of getting 1 ten = 16/51
possibility of getting a blackjack = 16 / 663
if you start with the 10 first the odds are the same:
possibility of getting 1 ten = 16/52 = 4/13
possibility of getting 1 ace = 4/51
possibility of getting a blackjack = 16 / 663
