Answers
Earl Darenz has been asked to choose a day from a week starting with the letter “S”, and we have found out the probability of it.
The number of days starting with “S” = Saturday and Sunday which is equal to 2 days.
A number of days in a week is equal to 7 days. Therefore the probability of choosing for El Darenz is 2/7.
Answer:
The probability of choosing a day starting with S is 2/7 or you can express this answer as 0.285 or 28.5%.
Step-by-step description:
Finding Opportunities for One Event
We have steps to follow to determine if an event is possible.
Describe all the events and possible consequences.
Based on the problem, we try to find opportunities to choose a day that starts on S week. "Choosing a date starting with S" is our event and the number of results is the total number of days in a week, 7.
2. Divide the number of events by
number of possible outcomes.
In our case, the number of events is 2 because the 2 days of the week start on S, Saturday and Sunday. Then, the total result is 7.
Chances are 2 ÷ 7 = 2/7. We can also express this response as 0.285 or 28.5%.
3. Combine every possible event
opportunities to ensure that
according to 1.
This is a step to check if our response is correct. The probability of all possible events should be equal to 1 or 100%. If it does not equal 1 or 100%, it means you have made a mistake. Go back and analyze the problem carefully. Then, repeat the steps.
For example, the chances of choosing a day starting with S in a week are 2/7. But the chances of choosing every other five days a week are 1/7.
1/7 + 1/7 + 1/7 + 1/7 + 1/7 + 2/7 = 7/7, which is 100%.
Our answer is correct.
