Percent error is calculated by the know amount minus the amount predicted over the known amount in absolute value so it would be |400-430/400| equaling to .075 which is 7.5% error

You ask a neighbor to water a sickly plant while you are on vacation. Without water the plant will die with probability 0.7. Wit
Lina20 [59]

Answer:

0.2416

Step-by-step explanation:

P(forgot to water | dead) = P(forgot and dead) / P(dead)  

->With water it will die with probability 0.45

P(watered and dead) =0.83 x 0.45 = 0.3735

->Without water the plant will die with probability 0.7

P(forgot and dead) = (1-0.83) x 0.7 => 0.17 x 0.7 =>0.119

P(dead) =  P(watered and dead) +P(forgot and dead)

P(dead) = 0.3735 + 0.119= 0.4925

P(forgot to water | dead) =0.119 / 0.4925= 0.2416

Therefore, the probability the neighbor forgot to water the plant is 0.2416

7p=231 \iff p = \dfrac{231}{7} = 33
