The probability of a penny and then without replacement a dime = 7/376
Explanation:Given:
A jar contains:
6 Pennies, 7 Dimes, 16 Nickels, and 19 Quarters
To find:
the probability when you reach into the jar and grab a penny and then without replacement a dime
Total coins = 6 + 7 + 16 + 19
Total coins = 48
Probability of picking a penny = number of pennies/total coins
Probability of picking a penny = 6/48
Probability of picking a dime after a penny without replacement:
Since we are not replacing the first pick, the total coins will reduce by 1
Total coin for 2nd pick = 48 - 1 = 47
Pr(dime after a penny without replacement) = number of dime/total coin
Pr(dime after a penny without replacement) = 7/47
The probability of a penny and then without replacement a dime = Probability of picking a penny ×
Pr(dime after a penny without replacement)
Answer:
<h2>radius = 9.77 yards</h2>Step-by-step explanation:
Since the pool is circular
Area of a circle = πr²
where
r is the radius
From the question
Area = 300 square yards
To find the radius substitute the value of the area into the above formula and solve for the radius
That's
300 = πr²
Divide both sides by π
We have
Find the square root of both sides
That's
r = 9.7720502
We have the final answer as
<h3>radius = 9.77 yards</h3>Hope this helps you
