A group of 72 children completed a survey on what kind of sport they like. The choices were: Chess, Swimming, and Football. Ever
hichkok12 [17]

Answer:

\dfrac{17}{72}

Step-by-step explanation:

From the given information:

Total number of students, n(U)=72

The choices were: Chess(C), Swimming(S), and Football(F).

Everyone liked at least one sport except 7 kids, n( C \cup F \cup S)'=7

Chess is not an active sport; and

10 children liked Chess only, n( C \cap F' \cap S')=10

The probability that a randomly-chosen child from this group does not like active kinds of sport is the Probability that a student plays chess only or like no kind of sport at all.

P( C \cup F \cup S)'+P(C \cap F' \cap S')=\dfrac{n( C \cup F \cup S)'+n(C \cap F' \cap S')}{n(U)} \\=\dfrac{10+7}{72} \\=\dfrac{17}{72}

<h3>What is a linear equation in two variables ?</h3>

An equation is linear if has highest degree of 1 and it has two variables.Generally they are in x and y.

For example -: 2x + 3y = 10

According to the given question a farmer has some hens and goats. He counts a total of 60 eyes and 86 feet between them.

Let us denote Hens by H and Goats by G.

We know both of them has 2 eyes each and we also know that a Hen has 2 legs and a Goat has 4 legs.

There fore the given data we can form two equations.

2H + 2G = 60 and 2H + 4G = 86.

Solving these two equations we have G = 13 and H = 17.
