Solution

Here we have the rule that

Probability(Any event)= Total favorable case/ total case

Here it is given that total cases are 189.

Now here

P(4 years of highschool or male )= P( 4 years of highschool )+ P(male)- P( 4 years of highschool and male)

Here total 4 years of highschool students are 62 and there are total 96 males and out of them there are total 30.

So required probability ( 4 years of highschool or male )= 62/189 + 96/189 - 30/189

=(62+96 -30)/189

= ( 158-30)1/89 = 128/180

that is our last required answer.
