Printable math worksheet asking students to calculate probabilities related to the days of the week.

Explanation:
We are given the 7 days of the week:
Monday, Tuesday, Wednesday, Friday, Thursday, Saturday, Sunday
Wait — let’s list them in correct order to avoid confusion:

Standard order:
1. Monday
2. Tuesday
3. Wednesday
4. Thursday
5. Friday
6. Saturday
7. Sunday

The problem lists them as:
MONDAY, TUESDAY, WEDNESDAY, FRIDAY, THURSDAY, SATURDAY, SUNDAY
But that seems scrambled — notice “FRIDAY” appears before “THURSDAY”, which is likely a typo in the layout, but the *set* of days is still the same 7 days. Since probability questions about “days of the week” always assume there are 7 equally likely days, we treat the sample space as the 7 standard days:
{Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday}

Now answer each question:

1. What is the probability of picking Friday at random?
There is 1 Friday out of 7 days.
→ Probability = 1/7

2. What is the probability of picking a day that begins with the letter "S"?
Days starting with “S”: Saturday, Sunday → 2 days
→ Probability = 2/7

3. What is the probability of picking a day that begins with the letter "T"?
Days starting with “T”: Tuesday, Thursday → 2 days
→ Probability = 2/7

4. What is the probability of picking a day that begins with the letter "M"?
Days starting with “M”: Monday → 1 day
→ Probability = 1/7

5. What is the probability of picking a weekend day?
Weekend days: Saturday, Sunday → 2 days
→ Probability = 2/7

6. What is the probability of picking a day with 6 letters total?
Let’s count letters in each day:
- Monday → 6 letters ✔
- Tuesday → 7
- Wednesday → 9
- Thursday → 8
- Friday → 6 ✔
- Saturday → 8
- Sunday → 6 ✔

So: Monday (6), Friday (6), Sunday (6) → 3 days
→ Probability = 3/7

Double-check spelling and letter counts:
- Monday = M-O-N-D-A-Y → 6 ✔
- Friday = F-R-I-D-A-Y → 6 ✔
- Sunday = S-U-N-D-A-Y → 6 ✔
Yes, exactly 3 days.

All probabilities are based on equally likely outcomes (1 out of 7), so fractions are correct.

Final Answer:
1. 1/7
2. 2/7
3. 2/7
4. 1/7
5. 2/7
6. 3/7
