What is the probability that: Enter your answer as a reduced fraction.(a) You draw a red marble and then a blue marble?Your answer is:(b) You draw a white marble and then a red marble?Your answer is:

Respuesta :

the possible outcomes are : red, white and blue. The total amount of marbles are 14.

The probability to get a red marble is

[tex]\frac{5}{14}[/tex]

to get a white one is

[tex]\frac{2}{14}=\frac{1}{7}[/tex]

and blue one is

[tex]\frac{7}{14}=\frac{1}{2}[/tex]

if we draw a red and then a blue one we get

[tex]\frac{5}{14}\cdot\frac{1}{2}=\frac{5}{28}[/tex]

and if we want a white and then a red one

[tex]\frac{1}{7}\cdot\frac{5}{14}=\frac{5}{98}[/tex]
