Question

The table shows the results of rolling a die with unequal faces find each experimental probability as a fraction in simplest form.Rolling a number other than 5?

Answer 1

Answer: 0.86

Explanation

The experimental probability P is found by:

$P=\frac{\text{ number of outcomes in event A}}{\text{ Total outcomes}}$

As we want to know the experimental probability of rolling a number other than 5, we can find the probability of rolling 5 and subtract it to 1. Thus, the number of outcomes we got of 5 is 14, while the total outcomes is the sum of all:

$\text{ Total outcomes}=26+10+12+9+14+29=100$

Then, the P(X=5) is:

$P(X=5)=\frac{14}{100}=0.14$

Finally, the P(X≠5) is:

$P(X\ne5)=1-0.14=0.86$
