Question

A bag has 12 red marbles, 20 green marbles, and 18 yellow marbles. Find the probability
of red marbles.​

Answer 1

$\huge \mathtt{\red{A}\pink{n}\blue{s}\purple{w}\green{e}\pink{r}}$

Red marbles= 12

Green marbles= 20

Yellow marbles= 18

Total number of marbles=12+20+18=50

$\sf{Probability= \frac{events}{total\: outcomes} }$

$\large \sf{= \frac{12}{50} = \frac{6}{25} \: \: or \: \: 0.25}$

$\large\mathtt{\color{red}{❥} \color{aqua}{Hope \: }\color{lime}{it \: }\color{magenta}{helps \: }\color{navy}{you \: }\green{.....}}$

Answer 2

Here,

Number of red marbles =12

Number of green marbles = 20

Number of yellow marbles = 18

P(E)=Number of trials in which the event happened / Total number of Trials

Probability of red marbles :-

P(E)= 12/12+20+18

P(E)=12/50
