Answer
(a) $\frac{2}{5}$
(b) $\frac{3}{5}$
(c) $1$
Work Step by Step
Since the bag contains $6$ red marbles and $4$ white marbles, the total number of marbles in the bag will be $6+4=10$ marbles.
(a) The question asks for the probability that a white marble is drawn.
There are $4$ white marbles out of $10$ total marbles.
We can use the formula for probability here, $P=\frac{n}{s}$.
$P=\frac{n}{s}$
$P=\frac{4}{10}$
$P=\frac{2}{5}$
(b) The question asks for the probability that a red marble is drawn.
There are $6$ red marbles out of $10$ total marbles.
We can use the formula for probability here, $P=\frac{n}{s}$.
$P=\frac{n}{s}$
$P=\frac{6}{10}$
$P=\frac{3}{5}$
(c) Sum = $\frac{2}{5}+\frac{3}{5}$ (Add the numerators together)
=$\frac{5}{5}$
= $1$
