You flip a coin 100 times in the air and find that it lands on heads 65 times. Determine the theoretical and experimental probab
scoundrel [369]

Answer:

The experimental probability --> \frac{13}{20}

The theoretical probability --> \frac{1}{2}

Step-by-step explanation:

<u>Key skills needed: Experimental vs theoretical probability, Fractions</u>

1) The first thing you need to understand is experimental probability vs theoretical probability. (Do not include this in your work!!)

- Theoretical probability is based on simple reasoning

- Experimental probability is based on the results a person gets (so the experiment you did by flipping the coin)

2) Now with this, let's start solving:

  1. Experimental probability ---> \frac{heads}{total} -->  You flipped the coin  a total of 100 times, so the denominator would be 100. 65 of those would be heads so 65 is our numerator.
  2. So our experimental probability is --> \frac{65}{100} --> Both have the factor of 5, so take the factor of 5 out of the numerator and denominator and you will get --> \frac{13}{20}
  3. Now onto theoretical probability --> \frac{heads}{total} --> There are 2 faces of a coin, 1 side is heads, and 1 side is tails --> The total number of faces is 2, so 2 is our denominator. There is only 1 side that is heads, so 1 is the numerator. This means  --> Our theoretical probability is \frac{1}{2}

<em>Hope you understood and have a nice day!! :D</em>
