Question

Based on the table below, predict the number of times the spinner landed on the blue section from a pool of 400 spins.

• A. 150
• B. 120
• C. 180
• D. 140

Answer 1

The correct option is B 120

From table, we observe:
Number of outcomes for the spinner top land on blue color after 100 spins = 30

∴ Experimental probability of the $\text{spinner landing on the blue color}=\frac{30}{100}$

So, prediction of spinner stopping on the blue section in 400 spins = Experimental probability × Number of trials

$=\frac{30}{100}\times 400$

= 120

Hence, the spinner will stop on the blue section nearly 120 times out of 400 times.
