we know that
The probability that "at least one" is the probability of exactly one, exactly 2, exactly 3, 4 and 5 contain salmonella.
The easiest way to solve this is to recognise that "at least one" is ALL 100% of the possibilities EXCEPT that none have salmonella.
If the probability that any one egg has 1/6 chance of salmonella
then
the probability that any one egg will not have salmonella = 5/6.
Therefore
for all 5 to not have salmonella
= (5/6)^5 = 3125 / 7776
= 0.401877 = 0.40 to 2 decimal places
REMEMBER this is the probability that NONE have salmonella
Therefore
the probability that at least one does = 1 - 0.40
= 0.60
the answer is
0.60 or 60%
Answer:
The slope-intercept is (0, 6).
Correct me if I’m wrong, I believe you have to add all of those numbers together. Then divide after and plug in those remaining digits
7/20 barrels of corn are the buffalo fed each day.
How to solve word problems?
It's actually fairly easy to solve word problems using a tried-and-true step-by-step approach.
- Aloud to yourself, read the issue.
- Make a Drawing.
- Ask yourself, "What am I looking for?"
- List the items that have been provided.
- Locate the key phrases.
- Solve.
- Verify your work.
Here are some actions to take:
- Recognize the issue, including all the terminology used to describe it. Recognize what you need to look for, Recognize the issue's context.
- Convert the issue into an equation. Give the unknown a variable (or variables) to symbolize, Indicate exactly what the variable stands for.
- Put the strategy into action and find a solution.
Given:
Elephants at the Norfolk zoo are fed = 1/2
Buffalo are fed 7/10 as much corn as the elephants = 7/10 * Elephants fed
= 7/10 * 1/2
= 7/20
Hence, 7/20 barrels of corn are the buffalo fed each day.
