Answer:
x=1
y=2
Step-by-step explanation:
Multiply the second equation by 2
and then solve!
The probability that all of them will be defective is 0.0000759375
<em><u>Explanation</u></em>
The general <u>Binomial Probability</u> formula is....
, where p is the probability of success, n is the total number of trials and r is the desired numbers of trials.
Given, the probability that a computer will be defective is 0.15 , so p = 0.15
Five computers are manufactured and we need to find the probability that all of them will be defective. That means, n = 5 and r = 5
Now according to the above formula....

So, the probability that all of them will be defective is 0.0000759375
Leave the whole number alone for now. Divide 41 by 80 and you get 0.5125
So your answer is 9.5125
1/12
This is because there are 12 potential outcomes of this scenario. Tails, 5 is just one of them.
