scoundrel [369]

Answer:

14 ( c ) = Caleb's

12 ( c + 10 ) = Sergio's

Step-by-step explanation:

Caleb lifted 14 boxes so you multiply 14 by c which is the weight of each box and for Sergio he lifted 12 boxes although his weighed 10 pounds more so you add 10 to c which would equal c + 10 multiplied by 12

Answer:

$\sf C. \quad \dfrac{1}{9}$

Step-by-step explanation:

Addition Law for Probability

$\sf P(A \cup B)=P(A)+P(B)-P(A \cap B)$

Given:

$\sf P(A)=\dfrac{1}{3}=\dfrac{3}{9}$

$\sf P(B)=\dfrac{2}{9}$

$\sf P(A \cup B)=\dfrac{4}{9}$

Substitute the given values into the formula and solve for P(A ∩ B):

$\implies \sf P(A \cup B) = P(A)+P(B)-P(A \cap B)$

$\implies \sf \dfrac{4}{9} = \sf \dfrac{3}{9}+\dfrac{2}{9}-P(A \cap B)$

$\implies \sf P(A \cap B) = \sf \dfrac{3}{9}+\dfrac{2}{9}-\dfrac{4}{9}$

$\implies \sf P(A \cap B) = \sf \dfrac{3+2-4}{9}$

$\implies \sf P(A \cap B) = \sf \dfrac{1}{9}$
