Answer:

\frac{-5}{24}

Step-by-step explanation:

let's use a common denominator! the easiest way is to multiply each side's numerator and denominator by the other's denominator. let's do this problem!

\frac{-7(8)}{12(8)} ----> \frac{-56}{96}

\frac{3(12)}{8(12)}-----> \frac{36}{96}

now that we have similar denominators, we can add the two numerators together!

-56 + 36 = -20!

\frac{-20}{96}

but wait! we can simplify it by dividing by 5 on both the numerator and denominator,

\frac{-5}{24}

2. What is the external probability of rolling a 4
Nataly_w [17]

Answer:

2. 1- Experimental probability of rolling a 4 = 40%

3. 2- Theoretical probability is 3%  greater than experimental probability.

Step-by-step explanation:

Experimental probability of rolling a 4 = 100 × \frac{8}{20}

                                                                  = 100 × 0.4

                                                                  = 40%

Experimental probability of getting at least one tail  = \frac{72}{100}

                                                                                    = 0.72

Theoretical probability of getting at least one tail  = \frac{3}{4}

                                                                                  = 0.75

Theoretical probability is 3%  greater than experimental probability.
