Answer:
0.24
Step-by-step explanation:
Total cards = 52
Face cards = heart {K,Q,J} , Spade {K,Q,J} , Club {K,Q,J} , Diamond{K,Q,J} = 12
Now we are given that You and a friend each randomly draw a card from a standard deck.
Probability that no one getting face card:
Favorable events = total cards - face cards = 52 -12= 40
So, probability that no one is getting face card =
Now we are supposed to find the probability that at least one of you is holding a face card
So, probability = 1 - probability that no one is getting face card
=1 - 0.76
= 0.24
So, probability that at least one of you is holding a face card is 0.24
The answer is D. 7/13

The median is 4.
Step-by-step explanation
if you layout all the number, you get
1,2,2,3,3,3,4,5,5,5,6,6,7
So, to find the median you find the number(s) right in the middle.
(Ex. 3,4,5; 4 is the median)
(Ex. 3,4,5,7; 4.5 is the answer)
The middle number of
is 4, so 4 is the median.
hope this helps. :)

X=incorrect answer
And probability of success to be denoted as P
Here X posses a binomial distribution along with 'r' and 'p'parameter

Trapezoid LPKB has area ...
A = (1/2)(b1 +b2)h = (1/2)(4 +20)(20) = 240 . . . . cm²
Triangle BPN has area ...
A = (1/2)bh = (1/2)(20)(20) = 200 . . . . cm²
Triangle BKN has a height that is 4/5 the height of triangle BPN, so will have 4/5 the area:
ΔBKN = (4/5)(200 cm²) = 160 cm²
The area of quadrilateral LPKB is that of trapezoid LPNB less the area of triangle BKN, so is ...
240 cm² - 160 cm² = 80 cm²
