Acertain group of students, the probability of a randomly chosen students is being male is 40%, the probability of the students studying in spanish it's 18%, and the probability that a student who is known to be male also studies spanish is 25%. what is thr probability of the student being both a male and studying spanish.
a. 10%
b. 45%
c. 4.5%
d. 7.2%

In this question, we're trying to find the probability of a male that also studies Spanish.

In this case, we know that:

With the information above, we can find the probability.

To find the probability, we would need to find how much of 40 is 25%.

To do this, we would multiply 0.4 (40%) by 0.25 (25%) to find our probability.

Solve:

The probability of a male that studies Spanish is 10%

Your answer would be A). 10%

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
