Question

a dice is rolled 200 times. how many times would you expect it to get an odd number?
50 100 117 142

Explanation:

Step1: Find odd probability on die

A standard die has 3 odd numbers (1,3,5) out of 6 total.
Probability $P(\text{odd}) = \frac{3}{6} = \frac{1}{2}$

Step2: Calculate expected occurrences

Multiply probability by total rolls.
Expected value $= 200 \times \frac{1}{2} = 100$

Answer:

100
