A ball is drawn randomly from a jar that contains 7 red balls, 5 white balls, and 4 yellow ball. Find the probability of the given event.

Respuesta :

Missing Part:

a. A red ball is drawn

b. A white ball is drawn

Answer:

a. [tex]P(Red) = 0.4375[/tex]

b. [tex]P(White) = 0.3125[/tex]

Step-by-step explanation:

Given

[tex]Red = 7[/tex]

[tex]White = 5[/tex]

[tex]Yellow = 4[/tex]

First, we need to calculate the total

[tex]Total = Red + White + Yellow[/tex]

[tex]Total = 7+5+4[/tex]

[tex]Total = 16[/tex]

Solving (a): Probability of Red.

This is calculated by dividing number of red balls by the total

So:

[tex]P(Red) = \frac{Red}{Total}[/tex]

[tex]P(Red) = \frac{7}{16}[/tex]

[tex]P(Red) = 0.4375[/tex]

Solving (a): Probability of White.

This is calculated by dividing number of white balls by the total

So:

[tex]P(White) = \frac{White}{Total}[/tex]

[tex]P(White) = \frac{5}{16}[/tex]

[tex]P(White) = 0.3125[/tex]
