Read each question carefully and calculate the experimental probability. Express your answers as a fraction in simplest form.
1. Sarah tossed a coin 50 times. It landed on heads 28 times and tails 22 times. What is the experimental probability of the coin landing on heads?
2. Alex rolled a standard six-sided die 30 times. The results are shown below:
Number rolled: 1, 2, 3, 4, 5, 6
Frequency: 5, 6, 4, 7, 3, 5
The experimental probability of rolling a 4 is .
The experimental probability of rolling an odd number is .
3. A spinner was spun 60 times. The results are recorded in the table:
Color: Red, Blue, Green, Yellow
Frequency: 15, 20, 10, 15
What is the experimental probability of the spinner landing on Blue?
1/4
1/3
5/12
1/2
4. Experimental probability is always exactly the same as theoretical probability.
True
False
5. A bag contains red, blue, and green marbles. David drew a marble from the bag 40 times, replacing it each time. He drew 12 red, 18 blue, and 10 green marbles. What is the experimental probability of drawing a red marble?
