A man has mislaid his wallet. He thinks there is a 0.4 chance that the wallet is somewhere in his bedroom, a 0.1 chance it is in

lana [24]

Answer:

a. Probability = 0.15

b. Probability = 0.3

Step-by-step explanation:

Given

$P(Bedroom) = 0.4$

$P(Kitchen) = 0.1$

$P(Bathroom) = 0.2$

$P(Living\ room) = 0.15$

Solving (a): Probability of being somewhere else

This is calculated by subtracting the sum of given probabilities from 1.

$Probability = 1 - (0.4 + 0.1 + 0.2 + 0.15)$

$Probability = 1 - 0.85$

$Probability = 0.15$

Solving (b): Probability of being in bedroom or kitchen

This is calculated as:

$Probability = P(Bedroom) + P(Kitchen)$

$Probability = 0.2 + 0.1$

$Probability = 0.3$

(1/125x^3)-1/3<br> Simplify the expression

bija089 [108]

Step-by-step explanation:

Simplify 1/125

1/125 . (x3))-1) ÷ 3

(x3

(———)-1) ÷ 3

125

3.1 x3 raised to the minus 1 st power = x( 3 * -1 ) = x-3

3.2 125 = 53 (125)-1 = (53)(-1) = (5)(-3)

x(-3)

——————— ÷ 3

(5)(-3)

x(-3)

Divide ——————— by 3

(5)(-3)
