A point that lies on the x-axis has its

  1. x-coordinate equal to zero
  2. y-coordinate equal to zero
  3. both coordinates equal
  4. coordinates undefined
Show answer and solution

Correct answer: B. y-coordinate equal to zero

1. Every point on the x-axis is at height zero. 2. So its **y-coordinate is zero** (form (x, 0)). 3. Similarly, a point on the y-axis has its x-coordinate zero. _Source: Karnataka SSLC (KSEEB) Class 10 Mathematics, Ch7 'Coordinate Geometry', §7.1_

    Choices
    1. P(F)
    2. P(E)
    3. P(E ∪ F)
  2. Answer
    not zero
    Choices
    1. not zero
    2. equal to 1
    3. less than P(E)
  3. Answer
    0 and 1
    Choices
    1. 0 and 1
    2. −1 and 1
    3. 0 and P(F)
Complete the statement
P(E|F) is defined as P(E ∩ F) divided by {0}, and it is only defined when P(F) is {1}. Its value always lies between {2}.
The definition the whole chapter is built on, including the condition that makes it meaningful. Source: syllabus Maths Part II, Ch 13 Probability.

Questions
  1. Statement is true
    Yes
    Statement
    P(E|F) = P(E ∩ F) ÷ P(F), provided P(F) ≠ 0.
  2. Statement is true
    No
    Statement
    P(E|F) can be greater than 1.
  3. Statement is true
    Yes
    Statement
    P(E′|F) = 1 − P(E|F).
  4. Statement is true
    No
    Statement
    P(E|F) is defined even when P(F) = 0.
  5. Statement is true
    Yes
    Statement
    0 ≤ P(E|F) ≤ 1 always holds.
