Question

The probability of NOT drawing a red marble out of a bag containing 3 blue, 2 green , 8 yellow , 4 red , and 3 orange marbles.

Answer 1

Answer:

$\frac{4}{5}$

Step-by-step explanation:

Total number of marbles

= 3+2+8+4+3

= 20 marbles

P(not red)

=

$\frac{3 + 2 + 8 + 3}{20} \\ = \frac{16}{20} \\ = \frac{4}{5}$

or P(not red)

=

$1 - \frac{4}{20} \\ = 1 - \frac{1}{5} \\ = \frac{4}{5}$
