Step-by-step explanation:
TRIANGLE 1
c = 2√5
= 2 × √5
= √4 × √5
= √20
a = 2
b = ?
b² = c² - a²
= √20² - 2²
= 20² - 4
= 400 - 4
= 396
b = √396
= √36 × √11
= 6 × √11
= 6 √11
TRIAGLE 2
a = 12
b = 6√11
= √396
c = ?
c² = a² + b²
= 12² + √396
= 144 + √396²
= 144 + 396
c = √540
= √36 × √15
= 6 × √15
= 6 √15

Given:
The number of male professors = 15.
The number of female professors = 9.
The number of male teaching assistants = 6.
The number of female teaching assistants = 12.
A person is selected randomly from the group.
Required:
We need to find the probability that the selected person is a professor or a male.
Explanation:
The total number of people in the group = 15+9+6+12 = 42
n(S) =The total number of people in the group

Let A be the event that the selected person is a professor or a male.
The number of people who are professors or male = 15+9+6 = 30
n(A)= The number of people who are professors or male.

Let P(A) be the probability that the selected person is a professor or a male.



Final answer:
The probability that the selected person is a professor or a male is 5/7.
