2.	If X and Y are two sets such that X has 40 elements, X ∪ Y has 60 elements andX ∩ Y has 10 elements, how many elements does Y have?
Answer» 30 Elements Given: n(X) = 40 n(X U Y) = 60 n(X ⋂ Y) = 10 To Find: n(Y) = ? Calculating: The FORMULA used to find the UNION of SETS is: n(X U Y) = n(X) + n(Y) - n(X ⋂ Y) Taking n(X) and - n(X ⋂ Y) to the other SIDE of the formula we get: n(Y) = n(X U Y) - n(X) + n(X ⋂ Y) Substituting all the values that are known to us in this formula we get: n(Y) = 60 - 40 + 10 n(Y) = 20 + 10 n(Y) = 30 Therefore, Element Y has 30 Elements.

If X and Y are two sets such that X has 40 elements, X ∪ Y has 60 elements andX ∩ Y has 10 elements, how many elements does Y have?

Answer»

30 Elements

Given:

n(X) = 40

n(X U Y) = 60

n(X ⋂ Y) = 10

To Find:

n(Y) = ?

Calculating:

The FORMULA used to find the UNION of SETS is:

n(X U Y) = n(X) + n(Y) - n(X ⋂ Y)

Taking n(X) and - n(X ⋂ Y) to the other SIDE of the formula we get:

n(Y) = n(X U Y) - n(X) + n(X ⋂ Y)

Substituting all the values that are known to us in this formula we get:

n(Y) = 60 - 40 + 10

n(Y) = 20 + 10

n(Y) = 30

Therefore, Element Y has 30 Elements.

8.	an unbiased die is thrown what is the probability of getting an even number and multiple of 3 2nd a number between 3 and 6
Answer» Answer: In a single throw of an unbiased dice, you can get any ONE of the OUTCOMES: 1, 2, 3, 4, 5, or 6. So, exhaustive number of cases = 6. (i) An even number is OBTAINED if you obtain any one of 2, 4, 6 as an outcome. So, favourable number of cases = 3. Thus, required probability = 3/6 = 1/2 (ii) A multiple of 3 is obtained if you obtain any one of 3, 6 as an outcome. So, favourable number of cases = 2 Thus, required probability = 2/6 = 1/3 (iii) An even number or a multiple of 3 is obtained in any of the following outcomes 2, 3, 4, 6. So, favourable number of cases = 4. Thus, required probability = 4/6 = 2/3 (iv) An even number and a multiple of 3 is obtained if you get 6 as an outcome. So, favourable number of cases = 1. Thus, required probability = 1/6

an unbiased die is thrown what is the probability of getting an even number and multiple of 3 2nd a number between 3 and 6

Answer»

Answer:

In a single throw of an unbiased dice, you can get any ONE of the OUTCOMES: 1, 2, 3, 4, 5, or 6.

So, exhaustive number of cases = 6.

(i) An even number is OBTAINED if you obtain any one of 2, 4, 6 as an outcome.

So, favourable number of cases = 3.

Thus, required probability = 3/6 = 1/2

(ii) A multiple of 3 is obtained if you obtain any one of 3, 6 as an outcome.

So, favourable number of cases = 2

Thus, required probability = 2/6 = 1/3

(iii) An even number or a multiple of 3 is obtained in any of the following outcomes 2, 3, 4, 6.

So, favourable number of cases = 4.

Thus, required probability = 4/6 = 2/3

(iv) An even number and a multiple of 3 is obtained if you get 6 as an outcome.

So, favourable number of cases = 1.

Thus, required probability = 1/6

Answer»

Answer:

Step-by-step explanation:

1. 0.4(3x - 1) = 0.5x +1

= 1.2x -0.4 = 0.5+1

=1.2x - 0.5x = 1+0.4

=0.7x =1.4

x = 1.4/0.7 = 2

2. 8x -7-3x = 6X -2x -3
