A tangent (here WZ in the question) to any circle (here O in the question) is a line segment that touches the circle at only one point (here B in the question) on circumference of circle, and the radius of the circle (here OB in the question) through this point is always perpendicular to that particular tangent.
In other words, Tangent (WZ) and Radius (OB) of any circle (O) always make a Right angle at point of intersection (B) on its circumference.
It means angle ∠OBZ would be a Right angle i.e. 90 degrees.
So, option B i.e. 90 degrees is the final answer.
Given:
Number of blue marbles = 6
Number of red marbles = 4
Number of green marbles = 4
Choose one marble without looking,
To find:
The probability that the selected marble is red or green.
Solution:
For the given problem,
Total outcomes = Total number of marbles
=
=
Favorable outcomes = Number of red or green marbles.
=
=
The probability that the selected marble is red or green, is
Therefore, the probability that the selected marble is red or green, is .
