Since they both have the same variables, just add the numbers and get 13. So therefore it is 13x
Answer:
15.5 I think

The probability that they both only speak Spanish is P = 0.005
<h3>How to find the probability?</h3>
There are 50 people.
We know that:
- 31 of these speak French.
- 2 speak French, German, and Spanish.
- 4 speak French and Spanish.
- 7 speak German and Spanish.
- 8 speak any of the lenguages.
- 10 speak german (and also other lenguages).
Then, the number that speaks only Spanish is:
50 - (31 + 10 + 8 - 3) = 4
(this is, the total number of people minus the ones that speak the other (or neither) lenguages, the "-3" appears there because 3 of the ones that speak German also speak French)
Then the probability that the first randomly selected person speaks Spanish is equal to the quotient between the number that speaks Spanish and the total number:
p = 4/50
For the next person we compute the probability in the same way, but this time there are 3 people that talk Spanish and 49 people in total:
q = 3/49
The joint probability is the product of the two individual ones:
P = (4/50)*(3/49) = 0.005
