Answer:
P(at least 1 wrong in 10) =0.5160
Step-by-step explanation:
Let A be the event that there is a problem in the proces. Then the probability of problem with the process is P ( A) = 0.07
Let B be the event that the process is without the problem. Then the probability of without problem is P ( B) = 0.93
Now we want to find the 10 successive points of event B. Since the events are independent we can find this as
P(B)+P(B)+P(B)+P(B)+P(B)+P(B)+P(B)+P(B)+P(B)+P(B)
or
P(B)^ 10= .93^10=0.48398
As we have to calculate at least 1 in 10 then we will subtract it from 1.
P(at least 1 wrong in 10) = = 1 - .93^10 =1- 0.48398=0.5160
Answer:
Step-by-step explanation:2:5 would be basically 2/5 and you could say that the ratio of
Girls to boys is 2:5
there are 5280 feet in a mile so 5280 times 3 is 15,840.
1 3/7 because 7+3 is equal to 10. also 20/14 is an improper fraction yet still acceptable
Answer:
Step-by-step explanation:
To write any decimal as a fraction you divide by 1 and multiply by a number (ranging from 10, 100, 1000 etc.) that will make 0.46 a whole number, this will explain:
Let x =
10x =
100x = this is our perfect fraction, now we simplify later
100x - 10x =
90x = this is to confirm both fractions are equal
x is the same as as as but here x = because a fraction has to have no decimals.
So 0.46 is equal any of these values, as a fraction, on the other hand, it's improperly equal to here I divided by 2 to bring down the proper fraction. (fraction at its simplest form)
