The spinner shown is divided into 8 equal sections. If the spinner is spun 144 times, what is a reasonable number of times to expect the spinner to land on an odd number?
what’s the answer
Since there are 8 sections on the spinner and 4 of them contain an odd number (1, 3, 5, 7), we can expect the spinner to land on an odd number about half of the time.
Therefore, a reasonable number of times to expect the spinner to land on an odd number out of 144 spins is approximately 72 times.
