Question

a box contains 3 blue,2 white,4 red marbles if a marble is drown at random from the box,what is the probability it will be (1)white (2)blue (3)red​

Answer 1

Answer:

blue

Step-by-step explanation:

3+2+4 = 9 ....... out of 9

blue 3/9 = 1/3

white 2/9

red = 4/9

Answer 2

Given

$\bold{Total \ no: \ of \ blue \ marbles} = 3$

$\bold{Total \ no: \ of \ white \ marbles} = 2$

$\bold{Total \ no: \ of \ red \ marbles} = 4$

$\bold{Total \ no: \ of \ marbles} = 3+2+4 = 9$

                                                                         

SOMETHING YOU NEED TO KNOW

$\boxed{ \sf {Probability \ of \ an \ outcome=\dfrac{Total \ no: \ of \ given \ outcomes}{Total \ no: \ of \ outcomes} }}}$

                                                                         

1) Probability of getting a white marble

$= \sf \dfrac{Total \ no: \ of \ white \ marbles}{Total \ no: \ of \ marbles}}$

$= \boxed{\boxed{\bold{ \dfrac{2}{9}}}}}}$

                                                                         

2) Probability of getting a blue marble

$= \sf \dfrac{Total \ no: \ of \ blue \ marbles}{Total \ no: \ of \ marbles}}$

$= \dfrac{3}{9}$

$= \boxed{\boxed{\bold{ \dfrac{1}{3}}}}}}$

                                                                         

3) Probability of getting a red marble

$= \sf \dfrac{Total \ no: \ of \ red \ marbles}{Total \ no: \ of \ marbles}}$

$= \boxed{\boxed{\bold{ \dfrac{4}{9}}}}}}$
