a) P(brown, then yellow)
b) P(green, then blue)
c) P(yellow, then yellow)
d) P(blue, then blue)
e) P(green, then not blue)
f) P(brown, then not green)

Answer 1

a) P(brown, then yellow) = 11% chance
b) P(green, then blue) = 3% chance
c) P(yellow, then yellow) = 13% chance
d) P(blue, then blue) = 4% chance
e) P(green, then not blue) = 10% chance
f) P(brown, then not green) = 25% chance
Make sure you check with a friend (I haven’t done probability in a while)
