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 answer is(6,9) i think
The answer would be 1/5. One bag weighs 5 pounds and 6 bags weigh 30 pounds. 5*6=30
Hope this helps!
Can u plz mark me as brainliest? I really need it!
It would be $0.50. Each Heads earns you $0.50 and if you pay $0.50 you have a chance of doubling your money.
