A bag of marbles has 3 red, 4 blue, and 5 white marbles in it. What is the probability of reaching in and selecting a blue marbl

goblinko [34]

Answer:

$P(B)=\frac{1}{3}$

Step-by-step explanation:

The number of red marbles in the bag is; $n(R)=3$ .

The number of blue marbles in the bag is; $n(B)=4$ .

The number of white marbles in the bag is; $n(W)=5$ .

The total number of marbles in the bag is: $n(S)=3+4+5=12$ .

The probability of selecting a blue marble is $P(B)=\frac{n(B)}{n(S)}$

We substitute the given information to obtain:

$P(B)=\frac{4}{12}$

We simplify to obtain:

$P(B)=\frac{1}{3}$
