Find the indicated probability.

natka813 [3]

Answer:

C) 0.179

Step-by-step explanation:

Since the trials are independent, this is a binomial distribution:

<u>Recall:</u>

Binomial Distribution --> $P(k)={n\choose k}p^kq^{n-k}$
$P(k)$ denotes the probability of $k$ successes in $n$ independent trials
$p^k$ denotes the probability of success on each of $k$ trials
$q^{n-k}$ denotes the probability of failure on the remaining $n-k$ trials
${n\choose k}=\frac{n!}{(n-k)!k!}$ denotes all possible ways to choose $k$ things out of $n$ things

<u>Given:</u>

$n=10$
$k=4$
$p^k=0.53^4$
$q^{n-k}=(1-0.53)^{10-4}=0.47^6$
${n\choose k}={10\choose 4}=\frac{10!}{(10-4)!4!}=210$

<u>Calculate:</u>

$P(4)=(210)(0.53^4)(0.47^6)=0.1786117069\approx0.179$

Therefore, the probability that the archer will get exactly 4 bull's-eyes with 10 arrows in any order is 0.179

What’s is the sum of the series?

STALIN [3.7K]

Answer:

Step-by-step explanation:

$\sum\limits_{k=1}^4(2k^2-4)\to a_k=2k^2-4\\\\for\ k=1:\\\\a_1=2(1)^2-4=2(1)-4=2-4=-2\\\\for\ k=2:\\\\a_2=2(2)^2-4=2(4)-4=8-4=4\\\\for\ k=3:\\\\a_3=2(3)^2-4=2(9)-4=18-4=14\\\\for\ k=4:\\\\a_4=2(4)^2-4=2(16)-4=32-4=28\\\\\sum\limits_{k=1}^4(2k^2-4)=-2+4+14+28=44$
