Question

in 100 spins, how many times would you expect to get an odd number?
5
1
4
2
3
75
40
60
50

Explanation:

Step1: Identify odd numbers

Odd numbers: 1, 3, 5

Step2: Count total/odd sections

Total sections: 5, Odd sections: 3

Step3: Calculate probability of odd

$\text{Probability} = \frac{3}{5} = 0.6$

Step4: Calculate expected spins

$\text{Expected} = 100 \times 0.6 = 60$

Wait, correction: Rechecking, the odd numbers are 1,3,5 (3 out of 5 equal sections). Wait no, wait the sections are equal? Yes, each is a fifth. So 3/5 of 100 is 60. I made a mistake earlier. Correct answer is 60.

Step1: List odd numbers on spinner

Odd values: 1, 3, 5

Step2: Count total/odd segments

Total segments: 5; Odd segments: 3

Step3: Find odd probability

$\text{Probability} = \frac{3}{5}$

Step4: Compute expected number

$100 \times \frac{3}{5} = 60$
