Answer:
0.706
Step-by-step explanation:
In this question, we are asked to calculate the probability that if 4 light bulbs are selected out of a total of 60, with 5 defective ones, all are good.
Firstly we need to find the probability of selecting a bulb that is not defective. Let’s call this P(g).
Since 5 are defective, it means 60-5 = 55 bulbs are not defective.
The probability of selecting a bulb not defective would be 55/60 = 11/12
Now, four are selected with claims that non are defective, the probability here would thus be 11/12 * 11/12 * 11/12 * 11/12 = 0.706066743827
To the nearest thousandth, we have 0.706
Answer:(-3 , -15)
X= -3 and Y= -15
Answer:
r = -189
Step-by-step explanation:
-13 - 8 = r/9
- 21 = r/9
r = 9 * -21
r = -189
