Chapter 10.6, Problem 8E

(a)

To determine

To calculate:

The number that is like to be spun on spinner

Answer to Problem 8E

The number that is like to be spun on spinner is $5$ .

Explanation of Solution

Given information:

  

Calculation:

The most likely the value to be spun on the spinner is the value of $x$ for that $P\left(x\right)$ is higher.

The probability of the spinning results shows the probability is greater for $5$ , more than $\frac{1}{4}$ .

(b)

To determine

To calculate:

The probability distribution of spinning even number

Answer to Problem 8E

The probability distribution of spinning even number is $0.25$ .

Explanation of Solution

Given information:

  

Calculation:

Add the probabilities corresponding to $10$ and $20$ . That gives probability of spinning even number.

The probability is as follows:

  $\begin{array}{l}P\left(evennumber\right)=P\left(10\right)+P\left(20\right)\\ P\left(evennumber\right)=0.17+0.08\\ P\left(evennumber\right)=0.25\end{array}$

The probability distribution of spinning even number is $0.25$ .
