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 greater than 2?

Answer 1

Answer

$P(X>2)=0.64$

Explanation

The experimental probability is given by:

$P=\frac{\text{ events for A}}{\text{ Total events}}$

As we want to know the probability of rolling a number greater than 2 then it is convenient to get the probability of rolling 1 and 2, and then subtracting both to 1.

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

0. Calculating the probability of rolling 1:

$P(X=1)=\frac{26}{100}=0.26$

2. Calculating the probability of rolling 2:

$P(X=2)=\frac{10}{100}=0.10$

3. Subtracting the previous probabilities from 1 to get P(X > 2):

$P(X>2)=1-0.1-0.26$$P(X>2)=1-0.36$$P(X>2)=0.64$
