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})
