Samir is an expert marksman. When he takes aim at a particular target on the shooting range, there is a 0.950.950, point, 95 pro
bearhunter [10]

The question is incomplete. Here is the complete question:

Samir is an expert marksman. When he takes aim at a particular target on the shooting range, there is a 0.95 probability that he will hit it. One day, Samir decides to attempt to hit  10 such targets in a row.

Assuming that Samir is equally likely to hit each of the 10 targets, what is the probability that he will miss at least one of them?

Answer:

40.13%

Step-by-step explanation:

Let 'A' be the event of not missing a target in 10 attempts.

Therefore, the complement of event 'A' is \overline A=\textrm{Missing a target at least once}

Now, Samir is equally likely to hit each of the 10 targets. Therefore, probability of hitting each target each time is same and equal to 0.95.

Now, P(A)=0.95^{10}=0.5987

We know that the sum of probability of an event and its complement is 1.

So, P(A)+P(\overline A)=1\\\\P(\overline A)=1-P(A)\\\\P(\overline A)=1-0.5987\\\\P(\overline A)=0.4013=40.13\%

Therefore, the probability of missing a target at least once in 10 attempts is 40.13%.

43 5/12 x 11 Please help
zzz [600]
The perimeter is the sum of side lengths. Opposite sides of a rectangle are the same length, so the perimeter is
  P = 11 +43 5/12 +11 +43 5/12
    = 2(11 +43 5/12)
    = 2(54 5/12)
  P = 108 5/6 . . . . feet

The area is the product of length and width. It doesn't matter which of the given dimensions you consider length or width, since you multiply them either way.
  A = 11 * 43 5/12
    = 473 +55/12
  A = 477 7/12 . . . . square feet
