Climate change poses significant challenges to cattle farming, a sector vital to global food security. Among the most pressing concerns is the increasing frequency and intensity of droughts. Reduced rainfall diminishes pasture quality and availability, limiting feed for livestock and increasing water scarcity. This can lead to decreased animal growth rates, reduced milk production, and increased mortality rates. Moreover, prolonged droughts can contribute to desertification, shrinking available grazing land and forcing farmers to adopt costly alternative feeding strategies.
   Beyond drought, other climate-related impacts include heat stress, which can significantly impact animal health and productivity. Rising temperatures can exacerbate heat stress, leading to ... Ver mais

      Em pesquisa sobre a eficiência de dois tipos de substratos S1 e S2 em determinada plantação experimental, foram considerados os seguintes eventos:
• A = “a planta atinge uma altura superior a 150 cm”;
• B = “o substrato empregado foi S1”;
• C = “o substrato empregado foi S2”;
• 30% das plantas se desenvolveram sobre substrato S1 e as restantes se desenvolveram sobre substrato S2;
• foram obtidas as seguintes probabilidades condicionais: P(A|B) = 0,3 e P(A|C) = 0,2. 

Com base nessas informações, julgue o seguinte item. 

P(B|A) = 0,3.
