The correct option is c.
The experimental probability of the spinner landing on a house is 1/5.
To find the experimental probability of the spinner landing on a house, you'll want to use the formula:
Experimental Probability = (Number of Favorable Outcomes) / (Total Number of Outcomes)
In this case, the favorable outcome is the spinner landing on the house, and the total number of outcomes is the total number of spins.
Step 1: Calculate the total number of spins
You mentioned that the spinner was spun 20 times, so the total number of outcomes is 20.
Step 2: Calculate the number of times the spinner landed on a house
You mentioned that the spinner landed on the house 4 times.
Step 3: Use the formula to calculate the experimental probability:
Experimental Probability = (Number of Favorable Outcomes) / (Total Number of Outcomes)
Experimental Probability = (4) / (20)
Now, simplify the fraction:
Experimental Probability = (1/5)
So, The answer is 1/5.
