show work pls tnx!

Answer 1

Answer:

The probability would be 5/15 or 1/3

Total = 7+3+5

= 15

yellow = 3

orange = 7

blue marbles = 5

Answer 2

Answer:

⇒Pgreen or yellow=5\11

Step-by-step explanation:

Probability here is the chance of selection out of a total. So, we need to first find the total number of marbles.

total

=

5

+

3

+

2

+

1

=

11

So there are

11

marbles total. The probability that we pick one of the

3

green marbles out of the

11

is simply that ratio:

P

green

=

3

11

Same idea for yellow:

P

yellow

=

2

11

The probability of picking either of these colors is simply the sum of their probabilities.

P

green or yellow

=

P

green

+

P

yellow

=

3

11

+

2

11

=

5

11
