Step-by-step explanation:
You ask a neighbor to water a sickly plant while you are on vacation. Without water the plant will die with probability 0.7. With water it will die with probability 0.4. You are 86 % certain the neighbor will remember to water the plant.
Prob for plant dying with water = prob that he waters but plant dies
= 0.86*0.4
= 0.344
Prob for plant dying without water = prob that he does not water and the plant dies
= (1-0.86)*0.7

LO = 17.5 + 17.5
LO = 35
