I can't give you all the answers to your hw.. but if there is a link somewhere on the page or in the left corner it says Kuta Software.. so maybe look that up for the answers?
Answer:
The expected number of ducks that escape unhurt is:
5
Step-by-step explanation:
First the process is binomial process. Having said this, we have 10 hunters, and 10 ducks flying overhead while the hunter take their shot at the same time.
By expected value, we mean average or mean. And the mean of a binomial distribution is:
Mean => E(x) = np.
We must also know that there is only two probability possibilities:
1. The hunter hits the duck (p)
2. The hunter misses the duck (1-p) = q.
Hence;
p = 1/2, and (1-p) = 1/2.
Therefore;
E(x) = np; where n is the total number of hunter.
E(x) = 10*(1/2) = 5
The expected number of ducks that escape unhurt is 5
Answer:
63
Step-by-step explanation:
In these 9 bags, each must have 7 gumdrops. So, we can add 7 nine times to itself. 7 + 7 + 7 + 7 + ... = 63
OR HERE'S A FASTER WAY *WINK WINK*
Instead of doing repeated addition, we can <u>multiply</u> 7 and 9 together.
<u>Why multiply?</u>
We're going to multiply 7 x 9 so that it means seven gumdrops for <em>each</em> of nine bags.
7 x 9 = 63.
