The probability of the student studying Spanish, if you know the students male will be 12.5%.
What is probability?
Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favorable outcomes / Number of sample
Given that in a certain group of students, the probability of a randomly chosen student being male is 40%, the probability of the students studying Spanish is 18%, and the probability of the student being male who studies Spanish is 5%.
The probability of the student studying Spanish, if you know the student male will be calculated as below:-
Divide the 5% of Spanish by 40% of males:
0.05 / 0.40 = 0.125
Change to a percent by multiplying by 100:
0.125 x 100 = 12.5%
Therefore, the probability of the student studying Spanish, if you know the students male will be 12.5%.
