3. A meeting of consuls was attended by 4 Americans and 2 Germans. If three consuls were selected at random one after the other, determine the values ofthe random variable G representing the number of Germans.

Answer»

ong>Given : A MEETING of consuls was attended by 4 Americans and 2 Germans.

three consuls were selected at random one after the other,

To Find : determine the values of the random variable G representing the number of Germans.

Solution:

Americans A = 4

Germans G = 2

Total = 6

3 out of 6 can be selected in ⁶C₃ = 20 Ways

Germans can be 0 , 1 or 2

three consuls were selected

G = 0 => ⁴C₃*²G₀ = 4 Ways

G = 1 => ⁴C₂*²G₁ = 12 Ways

G = 2 => ⁴C₁*²G₂ = 4 Ways

G P (G) G. P(G)

0 4/20 =0.2 0

1 12/20 =0.6 0.6

2 4/20 =0.2 0.4

Expected Value = ∑ G. P(G)

= 0 + 0.6 + 0.4

= 1

How much time is needed to fill the cistern????? step by step explanation neededplease don't spam :)

Answer»

ong>Answer:

LET the 3 taps be A, B and C.

A fills tank in 12 mins -> In 1 min A will FILL 1/12 of tank.

B fills tank in 15 mins -> In 1 min B will fill 1/15 of tank.

Lets say C can alone empty the tank in x mins -> In 1 min C will empty 1/x of tank.

According to question, if all taps are OPENED tank will fill in 20 mins.

In each min 1/20 tank is filled which is due to A, B and C. Now A and B fill the tank will C empty the tank.

1/12 + 1/15 - 1/x = 1/20

1/12 + 1/15 - 1/20 = 1/x

(5+4-3)/60 = 1/x

6/60 = 1/x

x = 10

$\underline{ \underline{ \Large \pmb{\mathit{ {Calculation:}} }} }$

Here, we are given the length, breadth and the height of the room that is 12 m, 10 m & 8m. We have to find the total cost of painting the 4 walls of a room. In order to find it, we NEED to calculate the area of the four walls of the room.

Answer» N:

solve : 5(5x-10)=15

To Find:

The value of x

Solution:

5(5x-10)=15

$= > 5(5x - 10) = 15$

$= > (5 \times 5x) - (5 \times 10) = 15$

$= > 25x - 50 = 15$

$= > 25x = 15 + 50$

$= > 25x = 65$

$= > x = \dfrac{65}{25}$

$= > x = 2.6$

Hence, the value of x is 2.6
