Answer:
B. 35%
Step-by-step explanation:
P(winning $1.00)=40%
P(winning $5.00)=20%
P(winning $10.00)=5%
In a probability distribution, the sum of the probability must always be equal to 1.
Therefore:
P(winning $0.00)=1-(40%+20%+5%)
=1-(0.4+0.2+0.05)
=1-0.65
=0.35
The probability of winning nothing at all is 35%.
Answer:
So to find ratio for questions like these we do x/y
So the ratio for the first one is 5/7
The ratio for the second is 12/7 or 1 5/7
Step-by-step explanation:
Hey there! The answer is 30 hours!
Work: 500 - 200 = 300
15 x 20 = 300
200 + 300 = 500
Answer:
None?
Step-by-step explanation:
Idk what the 6^3 x 2^6/2^3 means but 2^6 x 3^8 = 419904 and none of the other choices match this sorry.
Let the two numbers be x and y
As given, the difference of two numbers is 3, so
or 
....(1)
And their sum is 25, so
.....(2)
Putting x=3+y in equation (2)
As, x+y=25
So the two numbers are = 14 and 11
