A bag only contains 4 blue counters and 3 red counters. A box only contains 5 blue counters and 2 red counters. One counter is
taken at random from the bag and one counter is taken at
random from the box. Complete the tree diagram and work out
the probability of selecting two red counters.

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew

the answer is  

d.
