Answer:
0.575
Step-by-step explanation:
There are two types of probabilities:
1. Theoretical Probability
2. Experimental Probability
The probability based on mathematical theories is called theoretical probability. It is not always true. i.e. the probability of getting a head in a toss of coin is 1/2 or 0.5 or 50%
Experimental probability is based on experiments. Experimental probability is always going to change whenever the experiment is performed.
The theoretical probability of getting a head while tossing a coin will always be 50% while experimental probability might be different the next time, experiment is performed.
In this case, the experimental probability will be 23/40 or 0.575 ..
Answer:
9.99493
Step-by-step explanation:
You divide the circumference by pi to get the diameter. Then if you want the radius, you just simply cut the diameter in half!
