In a standard set of cards, the probability of drawing a red card or a face card is 73%
<h3>What is the probability?</h3>
In a standard deck of cards, there are 26 red cards. In that same deck, there will be 12 face cards.
The probability of picking either one is:
= (Number of face cards + Number of red cards) / Number of total cards
Solving gives:
= (12 + 26) / 52
= 38 / 52
= 73%

Answer:
4:1
Step-by-step explanation:
x+20 : y+20 = 5 : 2
(x+20)/(y+20) = 5/2
2(x+20) = 5(y+20)
2x+40 = 5y+100
2x = 5y+60 (1)
x-5 : y-5 = 5:1
(x-5)/(y-5) = 5/1
x-5 = 5(y-5)
x-5 = 5y-25
x = 5y-20 (2)
Solve (1) & (2) simultaneously,
2(5y-20) = 5y+60
10y-40 = 5y+60
5y = 100
y = 20
x = 5y-20
x = 5(20)-20 = 100-20
x = 80
x:y
80:20
