Question

A number from 14 to 21 is drawn at random p(odd number)

Answer 1

Step-by-step explanation

We consider the data set {14, 15, 16, 17, 18, 19, 20, 21}.

In this data set we have the following number of elements:

• n(even numbers) = 4,

,

• n(odd numbers) = 4,

,

• n(total) = 8.

The probability of drawing an odd number is given by:

`P(\text{odd number})=\frac{n(\text{odd numbers})}{n(\text{total\rparen}}=(4)/(8)=(1)/(2)=0.5.`Answer

P(odd number) = 0.5
