The table above represents the outcome of throwing a die 100 times. What is the probability of obtaining at least a 4?
  • A.
    (frac{1}{5})
  • B.
    (frac{1}{2})
  • C.
    (frac{2}{5})
  • D.
    (frac{3}{4})
Correct Answer: Option C
Explanation

Let E demote the event of obtaining at least a 4
Then n(E) = 16 + 10 + 14 = 40
Hence, prob (E) = (frac{n(E)}{n(S)})
( = frac{40}{100})
( = frac{2}{5})
