Answer:
1 /4
Step-by-step explanation:
Given that :
Let :
P(S) = probability of drawing a spade
Odds in favor of drawing a spade = 1:3 ; this could be interpreted as :
P(drawing a spade)/P(not drawing a spade) = 1:3
P(S) / P(S') = 1/ 3
P(S') = 1 - P(S)
P(S) / (1 - P(S)) = 1 / 3
Cross multiply :
3P(S) = 1 - P(S)
Collect like terms
3P(S) + P(S) = 1
4P(S) = 1
P(S) = 1/4
Hence, probability ratio of drawing a spade P(S) = 1/4
Answer:
The final amount would be about $365
Step-by-step explanation:
The formula for that would be A = P(1+i)^n
A = 300(1.05)^4
A = 300(1.21550625)
A = 364.651875
Answer:
Step-by-step explanation:
<u>The Volume of a Sphere
</u>
The volume of a sphere of radius r is given by:
A. )
If the diameter of the sphere is d, the radius is r=d/2. Substituting:
Operating
Simplifying
B.)
The diameter of the sphere is 2/3 cm, thus the volume is:
Operating:
