1. Since dividing 218 by n gives a remainder of 11, 218 - 11 = 207 is divisible by n :

207\equiv0\pmod{n}

2. Similarly, dividing 172 by n gives a remainder of 11, so 172 - 11 = 161 is divisible by n :

161\equiv0\pmod{n}

3. n must be a common divisor of 207 and 161. Find the greatest common divisor of 207 and 161:

- First, find the difference:

207 - 161 = 46

- Find the prime factorization of 46:

46 = 2 \times 23

- Prime factorization of 161:

161 = 7 \times 23

- Common factor is 23.

4. Therefore, the possible value of n should be 23 (since other divisions have factors that don't divide both). Now, divide n = 23 by 11:

23 \div 11 = 2 \, \text{R} \, 1

5. Thus, the remainder of dividing n by 11 is 1

A hotel in the Algarve had to offer 1 week of vacation to one of its employees as an Easter gift in a random choice. It is known that 80 people work in this hotel unit, 41 of whom are Portuguese and 39 are foreign nationals. There are 14 Portuguese men and 23 foreign women. Using what you know about conditional probability, check the probability that the gift was offered to a Portuguese citizen, knowing that it was a woman.
