Answer:

Justin got 51 questions correct

Step-by-step explanation:

  1. Find 85% of 60: 85% of 60 = \frac{85}{100} × \frac{60}{1}  
  2. \frac{85}{100} × \frac{60}{1} = \frac{5100}{100}  
  3. \frac{5100}{100} = \frac{51}{1} = 51  
  4. So, 85% of 60 = 51

I hope this helps!

If copies of all your computer data are stored on four independent hard disk​ drives, what is the probability that during a​ yea
Natasha2012 [34]

Answer:

P(Atleast\ 1) = 0.9999992

Step-by-step explanation:

Given

p = 3\% --- rate of hard disk drives failure

n = 4 --- number of hard disk drives

<em>See comment for complete question</em>

Required

P(Atleast\ 1)

First, calculate the probability that the none of the 4 selected is working;

P(none) = p^4

P(none) = (3\%)^4

P(none) = (0.03)^4

Using the complement rule, the probability that at least 1 is working is:

P(Atleast\ 1) = 1 - P(none)

This gives:

P(Atleast\ 1) = 1 - 0.03^4

P(Atleast\ 1) = 0.9999992
