Answer:
The probability is 0.5086
Step-by-step explanation:
The probability P that at least one of these three modules will fail to work properly is calculated as:
P = 1 - P'
Where P' is the probability that all the modules works properly. So, P' os calculated as:
P' = 0.9 * 0.84 * 0.65
P' = 0.4914
Because 0.9 is the probability that module 1 works properly, 0.84 is the probability that module 2 works properly and 0.65 is the probability that module 3 works properly.
Finally, the probability P that at least one of these three modules will fail to work properly is:
P = 1 - 0.4914
P = 0.5086
The cost of the brand less than 6 bags is less than 11.94
<h3>Functions and equations</h3>
If the cost y of a brand can be represented by the equation y=1.99x
where
- x represents the number of bags.
For a brand that costs less than 6 bags, we will substitute x = 6 into the function
y = 1.99(6)
y = 11.94
Hence the cost of the brand less than 6 bags is less than 11.94
