Abox contains 3 plain pencils and 1 pen. a second box contains 4 color pencils and 4 crayons. one item from each box is chosen at random. what is the probability that a pen from the first box and a crayon from the second box are selected? write your answer as a fraction in simplest form.

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
