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

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

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=(Number\:of\;Favorable\:outcome)/(Number\:of\:total\;outcome)=(4)/(12)=(1)/(3)`

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