4. Eddie flips 2 unfair coins each with P(H)= 2/5. MAKE A TREE DIAGRAM showing the possible outcomes with their probabilities. According to your
diagram, what is the probability he flips one heads and one tails?(order
doesn't matter)

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct

Bi’m pretty sure hope it works

The equation i believe is 4+ i am not sure about the part: the number of weeks in a group of days so i can't you on that part
