A car painting company has determined that the painting time of cars is uniformly distributed between 25 and 105 minutes. What i

Masteriza [31]

Answer:

$P=\frac{5}{16}$

Step-by-step explanation:

For a uniform distribution we have to:

$P (X\leq x) =\frac{x-a}{b-a}$ for x∈ (a, b)

$P (X\leq x) =0}$ for $x\leq a$

$P (X\leq x) =1}$ for $x\geq b$

In this case we have to:

a = 25 min and b = 105 min

We want to find:

$P (40 \leq X \leq 65)$

Then

$P (x_1 \leq X \leq x_2) = P(X \leq x_2) - P(X \leq x_1)$

$P (x_1 \leq X \leq x_2)= \frac{x_2 -x_1}{b-a}$

In this case:

$x_2 = 65\\\\x_1=40$

Therefore:

$P (40 \leq X \leq 65)=\frac{65 -40}{105-25}$

$P (40 \leq X \leq 65)=\frac{25}{80}$

$P (40 \leq X \leq 65)=\frac{5}{16}$
