A spinner has eight equal sections numbered from 1–8. Predict how many times the pointer will land on a 2 or a 5 if you spin the
spinner 60 times.
1 answer:
Answer:
15 times
Step-by-step explanation:
By spinning once, the probability of landing on 2 is 1/8
The probability of landing on 5 is 1/8
The probability of landing on 2 or 5 is 1/8 + 1/8 = 2/8 = 1/4
So spinning 60 times, the number of times we expect a landing on 2 or 5 will be ;
1/4 * 60 = 15 times
