Chapter 10.6, Problem 7E

(a)

To determine

To calculate:

The number that is like to be spun on spinner

Answer to Problem 7E

The number that is like to be spun on spinner is $2$ .

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 $2$ , more than $\frac{1}{4}$ .

(b)

To determine

To calculate:

The probability distribution of spinning even number

Answer to Problem 7E

The probability distribution of spinning even number is $0.6$ .

Explanation of Solution

Given information:

  

Calculation:

Add the probabilities corresponding to $2$ and $4$ . That gives probability of spinning even number.

The probability is as follows:

  $\begin{array}{l}P\left(evennumber\right)=P\left(2\right)+P\left(4\right)\\ P\left(evennumber\right)=0.35+0.25\\ P\left(evennumber\right)=0.6\end{array}$

The probability distribution of spinning even number is $0.6$ .
