Of the coffee makers sold in an appliance​ store, 4.0% have either a faulty switch or a defective​ cord, 2.5% have a faulty​ swi
lukranit [14]

Answer: Hence, Probability that a coffee maker will have a defective cord is 0.376=37.6%.

Step-by-step explanation:

Since we have given that

Let A be the event of getting a faulty switch.

Let B be the event of getting a defective cord.

Here, P(A∪B) = 4% = 0.04

P(A∩B) = 0.1% = 0.001

P(A) = 2.5% = 0.025

We need to find P(B):

As we know that

P(A\cup B)=P(A)+P(B)-P(A\cap B)\\\\0.04=P(A)+0.025-0.001\\\\0.04=P(A)+0.024\\\\P(A)=0.04-0.024=0.376

Hence, Probability that a coffee maker will have a defective cord is 0.376=37.6%.

What is the probability that a randomly chosen point on the grid below is in the blue area? A grid with 20 squares. 12 are shade
ELEN [110]

Answer:

Three-fifths

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The probability that a randomly chosen point on the grid below is in the blue area is equal to dividing the number of blue squares by the total number of squares

Let

x -----> the number of blue squares

y ----> the total number of squares

so

P=\frac{x}{y}

we have

x=12\\y=20

substitute

P=\frac{12}{20}

simplify

P=\frac{3}{5}

therefore

Three-fifths
