Can you be more specific? I need a question and I need a close up ! Lol but I’m trying to help.
Probability of getting an even number (2,4,6) out of (1,2,3,4,5,6) =3/6=1/2
The probability of getting x even number :
(using the binomial probability)
30Cx (1/2)^x . (1/2)^(30-x)
Answer:
253/1000, 23.5%
Step-by-step explanation:
X=numerator
y=denominator
the sum of numerator and denominator=x+y
we suggest this system of equations:
y=x-3
(x+5) / (y+5)=5/6
we solve this system of equation by substitution method.
(x+5) / (x-3+5)=5/6
(x+5) / (x+2)=5/6
6(x+5)=5(x+2)
6x+30=5x+10
6x-5x=10-30
x=-20
y=x-3=-20-3=-23
Teh sum of the numerator an denominator=-20+(-23)=-43
Answer: -43
Ken:
Ken's Age = 18
Elizabeth:
Elizabeth's Age = 2/3 x Ken's age
Elizabeth's Age = 2/3 x 18
Elizabeth's Age = 12
Clint:
-Note: At Clint's <em>next</em> birthday. So we need to subtract 1 from the age.
Clint's Age = (2 x Elizabeth's Age) - 1
Clint's Age = (2 x 12) - 1
Clint's Age = 24 - 1
Clint's Age = 23 right now
Hope this helps!! :)
