Answer:
B
Step-by-step explanation:
Because -1/2 is not a whole number so b is the only answer left
77.2%
To find the probably and at least on you must find the probability of none and subtract from one.
The probability of none can be found like so:
(5+6 over 5+6+7)^3 = .228
1 - .228 = .772
Hope this helps!
Answer:
5 1/3 hours.
Step-by-step explanation:
Ashley prepares 1 bag in 2/3 minutes.
One friend takes 2/3 + 3/4 * 2/3 = 7/6 minutes to make 1 bag.
4 of her friends can make 1 bag in 7/6 * 1/4 = 7/24 minutes.
If it takes x minutes for Ashley and 4 friends to make one bag then we have:
1 / 2/3 + 1 / 7/24 = 1 / x
3/2 + 24/7 = 1/x
Multiply through by 14x:
21x + 48x = 14
x = 14/69 minutes.
So the time to make 1575 bags = 1575 * 14/69
= 320 minutes.
