YES YES i am finally happy

Step-by-step explanation:

Tbh i dont have like any social media but i heard it is bad so I’m glad you are happy

Step-by-step explanation:

0.28

Step-by-step explanation:

High-quality soil gives seed: 0.8 chance of survival

Medium-quality soil gives seed : 0.3 chance of survival

Low-quality soil gives seed: 0.1 chance of survival

Proportions/frequency of soils:

High-quality soil = 30% = 0.3

Medium-quality soil = 20% = 0.2

Low-quality soil = 50% = 0.5

probability of a seed landing on a particular soil type ∝ frequency of that type in the  habitat

probability that a seed dies before landing = 0.2

A) The overall probability of seed survival

first we have to determine the probability of seed survival if it lands

= ∑ (frequency of soil * chance of seed survival)

= (0.8 * 0.3) + ( 0.3 * 0.2 ) + ( 0.1 * 0.5 ) = 0.35

hence overall probability of seed survival

= ( 1 - 0.2 ) * 0.35 = 0.28
