Answer:
The probability of the event of identifying both the defective bulb in the second attempt is .
Step-by-step explanation:
The number of good light bulbs is 5 and the number of defective bulbs is 2.
It is provided that when a defective bulb is found in the inspection it is disposed.
If a defective bulb is found in the first trial the probability of his event is .
Now the remaining number of bulbs is 6.
If a defective bulb is found in the second trial the probability of his event is .
So the probability of identifying both the defective bulb in the second attempt is:
P (Selecting a defective bulb in 1st attempt) × P (Selecting a defective bulb in 2nd attempt) =
Thus, the probability of the event of identifying both the defective bulb in the second attempt is .

Step-by-step explanation:
Based on the cost of the adult tickets and the children's ticket, the expression that can find the amount raised is<u> 8x + 3y.</u>
Also if those number of tickets were sold, the amount realized would be <u>$3,054.</u>
The total amount raised can be found as:
<em>= (Number of adult tickets x price of adult tickets) + (Number of children's tickets x price of children's tickets)</em>
Assuming the adult tickets are x and the children's tickets are y, the equation would be:
= (x × 8) + (y × 3)
= 8x + 3y
If 240 adult tickets and 378 children's tickets are sold, the amount realized would be:
= 8x + 3y
= (8 x 240) + (3 x 378)
= $3,054
In conclusion, the relevant expression is 8x + 3y and the amount raised would be $3,054.

X + 4 > = 1/2(x - 3)
x + 4 > = 1/2x - 3/2
2x + 8 > = x - 3
2x - x > = -3 - 8
x > = - 11
so not included would be any number that is less then or equal to -11.....such as -11, -12, -13....etc
