If a coin is tossed 100 times and lands on heads 60 times, what is the experimental probability of getting tails?
0.4
0.6
0.5
1.0
คำอธิบาย
The coin landed on heads 60 times. Since the total trials are 100 times, the coin landed on tails 40 times. Therefore the experimental probability is 40/100= 0.4.
