Solution :
It is given that P(x) is said to be complete or proper probability distribution if it satisfies the following two ways :
1. 
2. 
Now consider,
⇒ 
⇒ 
⇒ 
⇒ 
= 0.2
Therefore, the value of T is 0.2
Thus, option (c) is correct.
Answer:
Volume required = 100mL
Step-by-step explanation:
Let the volume of 30% solution required be = V mL
Amount of solute in V mL of solution = 30% of V = 0.3V...............(i)
This amount is also present in 150 mL of 20% solution
For 150 mL of 20% solution we have amount of solute = 150 mL X 20%
= 30..............(ii)
Thus equating i and ii we get
0.3V = 30
Thus V =100 mL
Answer:
1. y = 4
2. x = 10
3. n = 6
4. m = 4
5. h = 2
Step-by-step explanation:
Hope this helps!!
x + 2x - x - 1
- Substitute 2 for x into the expression.
(2) + 2(2) - (2) - 1
(2) + (4) - (2) - 1
- Solve from left to right.
- (2 + 4) - 2 - 1 = 6 - 2 - 1
6 - 2 - 1
- Solve from left to right.
- (6 - 2) - 1 = 4 - 1
4 - 1 = 3
<h3>Your answer is 3.</h3>
Total number of outcomes of 7 from 10 = 10*9*8 / 3*2*1 = 120
probability of each outcoe is 0.85^7* (0.15)^(3) = 0.0010819
Required probability = 120 * 0.0010819 = 0.1298
