Question

A spinner has 4 equal sections. after 12 spins, the spinner landed on section a 4 times, section b 5 times, section c 2 times, and section d 1 time. what is the experimental probability of the spinner stopping on section a?

Answer 1

Answer:

The Experimental Probability of the spinner stopping on Section A is 1/3.

Step-by-step explanation:

Number of time spinner landed on section A = 4

Number of time spinner landed on section B = 5

Number of time spinner landed on section C = 2

Number of time spinner landed on section D = 1

Total Number of spins = 12

$Probability=\frac{Number\:of\;Favorable\:outcome}{Number\:of\:total\;outcome}=\frac{4}{12}=\frac{1}{3}$

Therefore, The Experimental Probability of the spinner stopping on Section A is 1/3.
