( * serious and meaningful answer expected*) [ It's not just for maths. but for all of the subjects...... INCLUDING biology. ]

As A and B are mutually exclusive therefore P(A intersection B) = 0 And P(A)= 1- P(not A) P(A)= 1-0.65 P(A) =0.35 Now by addition theorem, P(AUB) = P(A) +P(B) - P (A intersection B) 0.93= 0.35+ P(B)-0 P(B)= 0.58 Ans

Ankit Singh 7 years ago

, expressing their slopes as negative reciprocals is not mathematically possible. The slope of vertical lines is undefined, and the negative reciprocal of a horizontal line (slope 0) is also undefined. ... These lines are perpendicular since their slopes are negative reciprocals.
