Question

he predicts that 60 of those spins will result in the spinner landing on the section labeled 3. based on the theoretical probability, which best describes elijah’s prediction? elijah’s prediction is exact because 180 ÷ 3 = 60. elijah’s prediction is exact because 180 × \frac{1}{3} \approx 60.

Explanation:

Step1: Analyze the spinner

The spinner is divided into 4 equal sections (labeled 1, 2, 3, 4). So the probability of landing on section 3 is $\frac{1}{4}$. Wait, but the options mention 180 spins? Wait, maybe the total number of spins is 180? Wait, let's re - examine. Wait, the problem says "60 of those spins will result in the spinner landing on the section labeled 3". Let's check the options. One option says $180\times\frac{1}{3}\approx60$? Wait, no, the spinner has 4 sections? Wait, maybe I misread. Wait, the spinner in the image is divided into 4 equal parts? Wait, no, maybe it's divided into 3? Wait, no, the labels are 1,2,3,4, so 4 equal sections. Wait, but the options have a fraction of $\frac{1}{3}$. Wait, maybe the spinner is divided into 3 equal sections? Wait, maybe the image is different. Wait, let's assume that the probability of landing on 3 is $\frac{1}{3}$. Wait, no, let's think again.

Wait, the correct approach: If the spinner has $n$ equal sections, the probability of landing on a specific section is $\frac{1}{n}$. Then, the expected number of times it lands on that section in $N$ spins is $N\times\frac{1}{n}$.

Looking at the options, one option is "Elijah’s prediction is exact because $180\times\frac{1}{3}\approx60$". Wait, if the total number of spins is 180, and the probability of landing on 3 is $\frac{1}{3}$, then the expected number is $180\times\frac{1}{3}=60$. So let's verify:

Step2: Calculate the expected number

If the probability of landing on section 3 is $p = \frac{1}{3}$ (maybe the spinner is divided into 3 equal sections? Wait, the labels are 1,2,3,4, but maybe it's a different division. Wait, maybe the question has a typo, but according to the option, if we take $N = 180$ spins, and $p=\frac{1}{3}$, then the expected number of times landing on 3 is $180\times\frac{1}{3}=60$. So the correct option is the one with $180\times\frac{1}{3}\approx60$ (but actually, it's exact here, $180\times\frac{1}{3}=60$).

Answer:

The correct option is the one stating "Elijah’s prediction is exact because $180\times\frac{1}{3}\approx60$" (more precisely, $180\times\frac{1}{3}=60$).
