nick likes to go on canoe trips, and on each trip he purchases oars to keep as souvenirs. his collection of oars is organized by decade and type of wood. what is the probability that a randomly selected oar was made from ash wood given that the oar was purchased in the 2020s? simplify any fractions.
Answer
Explanation:
Step1: Encontrar el total de remos comprados en los 2020s
Sumamos los remos de madera de abeto y de fresno comprados en los 2020s. $2 + 2=4$.
Step2: Encontrar el número de remos de madera de fresno comprados en los 2020s
El número de remos de madera de fresno comprados en los 2020s es 2.
Step3: Calcular la probabilidad condicional
La probabilidad condicional $P(A|B)$ se calcula como $\frac{n(A\cap B)}{n(B)}$. Aquí, $A$ es el evento de que el remo sea de madera de fresno y $B$ es el evento de que el remo sea comprado en los 2020s. Entonces $P(A|B)=\frac{2}{4}=\frac{1}{2}$.
Answer:
$\frac{1}{2}$
