A circular spinner is divided into 5 equal parts, if the spinners spun 3 times what is the probability that an even number is spun all 3 times?​

A circular spinner is divided into 5 equal parts if the spinners spun 3 times what is the probability that an even number is spun all 3 times class=

Respuesta :

Answer:

d. 8/125

Step-by-step explanation:

If each part is numbered from 1 to 5, then 2 of the parts are even (2 and 4).  So the probability of landing on an even number is 2/5.

The probability of landing on an even number 3 times is:

P = (2/5)^3

P = 8/125

When a spinner is divided into equal parts, each segment in the spinner has an equal probability. The probability that the outcomes of the 3 spin is even is 8/125

Let the numbers on the spinner be:

[tex]S = \{1,2,3,4,5\}[/tex]

[tex]n(S) = 5[/tex]

The even numbers are:

[tex]E =\{2,4\}[/tex]

[tex]n(E) = 2[/tex]

The probability of 1 even number is:

[tex]P(E) = \frac{n(E)}{n(S)}[/tex]

So, we have:

[tex]P(E) = \frac{2}{5}[/tex]

In three spin, the probability that all outcomes are even is:

[tex]P(Even) = P(E) \times P(E) \times P(E)[/tex]

[tex]P(Even) = \frac{2}{5} \times \frac{2}{5} \times \frac{2}{5}[/tex]

[tex]P(Even) = \frac{8}{125}[/tex]

Hence, the probability that the outcomes of the 3 spin is even is 8/125
