If a die is thrown and 'getting an odd number' is success, then $p$ and $q$ are:
A$p = 1/3, q = 2/3$
B$p = 1/2, q = 1/2$
C$p = 1, q = 0$
D$p = 2/3, q = 1/3$
Answer & Solution
Correct answer: B. $p = 1/2, q = 1/2$
Odd numbers on a die: {1, 3, 5} ⇒ 3 favourable out of 6. $p = 3/6 = 1/2$, $q = 1 - p = 1/2$.
