A coin is tossed 40 times and shows heads 23 times. Calculate the experimental probability of the coin showing heads.
Over [174]

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: The answer is option C: 10cm, 6cm and 8cm

Step-by-step explanation: A right angled triangle has an hypotenuse (the longest of all three sides) facing the 90 degree angle. Also a right angled triangle can be solved by means of the Pythagoras theorem which states that;

AC^2 = AB^2 + BC^2

Where AC is the hypotenuse (10cm) and AB (6cm) and BC (10cm) are the other two sides.

If that is the case, we can insert the values as given in option C to know whether or not they make up a right angled triangle. Therefore

10^2 = 6^2 + 8^2

100 = 36 + 64

100 = 100

Therefore the side lengths 10cm, 6cm and 8cm satisfies the requirements for a right angled triangle
