You can expect the spinner to land an odd number 25 times out of 50.

I would expect it to land on a number of 4 or higher 50% of the time or roughly 24 times.
36 times. But also, you might get the opposite result 36 times.
P(4) = 1/6 x 84 = 14 times.

A regular or even an irregular dodecagon is a 12 sided polygon whose interior angles add up to 1800 degrees
When rolling a fair six-sided die, the probability of rolling a 4 is ( \frac{1}{6} ). If Adam rolls the die 96 times, you can expect him to roll a 4 approximately ( 96 \times \frac{1}{6} = 16 ) times. Thus, he can expect to roll a 4 about 16 times.
Suppose A is the event {rolling a 6-sided die 20 times and getting a 5} Then A', the complement of A, is the event {rolling a 6-sided die 20 times and not getting a 5 any times} So Pr(A) = 1 - Pr(A') = 1 - (5/6)20 = 1 - 0.026084 = 0.973916 (to 6 dp)
