Two cards are chosen at random without replacement from a well-shuffled pack. what is the probability that the second card drawn

is also a king given that the first one drawn was a king?

Having drawn one king, there are 3 kings remaining and a total of 51 cards. Therefore the probability of drawing another king is 3/51 = 1/17.

When the function below is graphed, how many x-intercepts does it have?y = 4x2 - 12x + 9?

Sladkaya [172]

Only x-intercept because if you want to know about x-intercepts so y will be zero (y=0)
then 0 =4x^2 -12x + 9
0=(2x-3)(2x-3)
0=2x-3
so x=3/2 that is x-intercept

Explain why 1/2 is not equivalent to 2/5.

juin [17]

Find ing the common denominator would make it 10.
for 1/2 to get to 10 you have to multiply by 5
1/2x5= 5/10
then you have to convert 2/5 to get the denominator to be 10
so you multiply 2/5 by 2
2/5x2= 4/10
5/10 is greater than 4/10

Two different airlines have a flight from Los Angeles to New York that departs each weekday morning at a certain time. Suppose t

marusya05 [52]

Answer: 0.8167

Step-by-step explanation:

Let E denotes the event that the first airline's flight is fully booked on a particular day, and F denotes the event that the second airline's flight is fully booked on that same day.

Given : P(E) = 0.7, P(F) = 0.6, and P(E ∩ F) = 0.49.

Then, by conditional probability formula , we have

$P(E|F)=\dfrac{P(\cap F)}{P(F)}\\\\=\dfrac{0.49}{0.6}=0.816666666667\approx0.8167$

Hence, the probability that the first airline's flight is fully booked given that the second airline's flight is fully booked.= 0.8167
