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

`P(X>2)=0.64`

Step-by-step 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)=(26)/(100)=0.26`

2. Calculating the probability of rolling 2:

`P(X=2)=(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`
