Use the following scenario for all questions. The marketing manager of a grocery store observed customers going to the baby’s section. She found that 62% of all customers buy buby formula, 52% of all the customers buy diapers and 38% of all customers buy both baby formula and diapers. Use B to denote the event that a randomly selected customer buys baby formula and D to denote the event that a randomly selected customer buys diaper. Thus the information given above can be written as P(B)=0.62, P(D)=0.52 and P(B∩D)=0.38. What is the probability that a randomly selected customer buys either baby formula or diaper?

76% probability that a randomly selected customer buys either baby formula or diaper

Step-by-step explanation

We solve this problem building the Venn's diagram of these probabilities.

There are two events, events B and D.

We have that:

In which P(b) is the probability of only b and is the probability of both B and D.

By the same logic, we have that:

P(B)=0.62, P(D)=0.52 and P(B∩D)=0.38.

So

And

What is the probability that a randomly selected customer buys either baby formula or diaper?

76% probability that a randomly selected customer buys either baby formula or diaper

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
