Question

I a bag 5 red balls and 3 white balls and 2 blue balls than find the probability of a red ball

Answer 1

Answer:

Total no.of balls is 5+3+2=10

No .of red balls is 5

The probabilty is 5/10 = 1/2

Answer 2

Given

$\bold{Total \ number \ of \ red \ balls} = 5$

$\bold{Total \ number \ of \ white \ balls} = 3$

$\bold{Total \ number \ of \ blue \ balls} = 2$

$\implies \bold{Total \ number \ of \ balls}$

$= 5+3+2$

$= 10$

SOMETHING YOU NEED TO KNOW

$\sf Probability = \dfrac{Given \ outcome}{Total \ no: \ of \ outcomes}$

$\implies \bold{Probability \ of \ getting \ a \ red \ ball} = \bold{\dfrac{Total \ number \ of \ red \ balls}{Total \ number \ of \ balls} }$

$= \dfrac{5}{10}$

$= \boxed{\boxed{\bold{ \dfrac{1}{2}}}}}}$
