Owen knows he only has three pencils in his backpack, and they are all yellow. He reaches into his backpack without looking and takes out pencil. What is the probability that the pencil was yellow?

100%

Step-by-step explanation:

The problem states that all pencils are yellow and no other color, so the only outcome is yellow.

2x+15=33

Step-by-step explanation:

Computation of the equation that could be solved to find the number of days Jerry has been doing sit-ups, not counting the first day

Based on the information given the EQUATION will be :

2x+15=33

Where,

x represent Jerry Sit up numbers of days excluding the first day

2x represent the additional 2 more sit ups

2x +15 represent the total number of sit up that was done after the first day

2x+15=33 represent the total 33 sit-ups that jerry did today

Therefore the EQUATION that could be solved to find the number of days Jerry has been doing sit-ups, not counting the first day will be 2x+15=33
