Question 1 • HCISD-Mathematical Models with Applications B-CR SUMMER

Alina has a spinner that has 5 equal sections: red, blue, green, purple, and orange. She spins the spinner 200 times. About how many times should Alina expect the spinner to land on either purple or orange?

Answer
A
40
B
80
C
100
D
120

Explanation

Purple and orange are 2 of the spinner’s 5 equal sections, so the probability of landing on either color is 2/5. Multiply 200 spins by 2/5: 200 × 2/5 = 80. Alina should expect about 80 spins to land on purple or orange.
