At tech high there are three math teachers, mary, tom, and alex. all students at tech high take math, with 21% taking class with mary, 15% with tom, and 64% taking class with alex. every year 4% of mary’s students fail, 6% of tom’s students fail, and 13% of alex’s student fail. what is the probability that a tech high student fails math? if needed, round to four decimal places.

The probability that a Tech High student fails math is 0.1006

Step-by-step explanation:

21% students are taking class with Mary.

Every year 4% of Mary’s students fail,

15% students are taking class with Tom

Every year 6% of Tom’s students fail.

64% students are taking class with Alex

Every year 13% of Alex's students fail.

Now we are supposed to find the probability that a Tech High student fails math.

Hence the probability that a Tech High student fails math is 0.1006
