a farmer sells 7.6 kg of apples and pears at the Farmers Market. Two-fifths of this weight is Apple's, and the rest is pairs. Ho

1/5 = 20% so... 2/5 = 40%
40% of 7.6 is 3.04
Subtract 3.04 from 7.6, you get 4.56

The farmer sells 4.56 kilograms of pears at the Farmers Market.

A card is drawn from a well shuffled deck of 52 cards. Find the probability that the card is a red card or a 2.

tamaranim1 [39]

$|\Omega|=52$

There are 26 red cards and four 2's. But two 2's are red, so $|A|=26+4-2=28$

$P(A)=\dfrac{28}{52}=\dfrac{7}{13}\approx54\%$

Suppose that 45% of people have dogs. If two people are randomly chosen, what is the probability that they both have a dog

mylen [45]

Answer:

$P(Dogs) = 0.2025$

Step-by-step explanation:

Given

$Proportion, p = 45\%$

Required

Probability of two people having dog

First, we have to convert the given parameter to decimal

$p = \frac{45}{100}$

$p = 0.45$

Let P(Dogs) represent the required probability;

This is calculated as thus;

<em>P(Dogs) = Probability of first person having a dog * Probability of second person having a dog</em>

<em />

$P(Dogs) = p * p$

$P(Dogs) = 0.45 * 0.45$

$P(Dogs) = 0.45^2$

$P(Dogs) = 0.2025$

<em>Hence, the probability of 2 people having a dog is </em> $P(Dogs) = 0.2025$ <em />
