green and 4 pencils are brown

f. If a pencil is picked at random, what is the probability that the pencil will be red or green or orange?

g. If a pencil is picked at random, what is the probability that the pencil will
NOT be orange?

'h. If a pencil is picked at random, what is the probability that the pencil will
NOT be blue or red?

Answer 1

g) a) 11/14

f) 9/14

h) 12/14

Explanation:

Probability is just the amount of the specified object over the total amount of objects.

Amount of Red : 2

Amount of Orange: 5

Amount of Green: 3

Amount of Brown: 4

Total: 14

*Formula: (Specified Object)/(Total)*

F) Chances of Red or Orange or Green

=(2+5+4)/14

=11/14

G) NOT be orange

*Formula: (Total)-(Specified)/(Total)*

=(14-5)/14

=9/14

H) NOT blue or red

*Formula: (Total)-(Specified)/(Total)*

=14-(2+0) (*There is a 0 there because the question asked to solve for blue pencils as well, and there are 0 blue pencils*)

= 12/14

Answer 2

Explanation:

F. 5/7 chance

G. 9/14 chance

H. You did not mention a blue color in the question.
