Telemarketing. the probability that a call will reach a live person is 0.2. the calls are independent. (a) a telemarketer places

Sergeeva-Olga [200]

Solution: Telemarketing. the probability that a call will reach a live person is 0.2. the calls are independent. (a) a telemarketer places 5 calls. what is the probability that none of them reaches a live person.

Answer: The given random experiment can be considered as binomial experiment with probability of success = 0.2 and number of trials = 5

Therefore, we have:

$n=5,p=0.2,q=(1-p)=1-0.2=0.8$

Let x be the number calls that reach to live person.

We have to find $P(x=0)$

Using the binomial probability distribution, we have:

$P(x=0)=\binom{5}{0}0.2^{0} (1-0.2)^{5-0}$

$=1 \times 1 \times 0.8^{5}$

$=0.3277$

Therefore, the probability that none of them reaches a live person is 0.3277

An unknown number b is 10 more than an unknown number k. the number b is also k less than 8. the equations to find k and b are s

Dmitriy789 [7]

Just add the two equations together.
2b = 18
b = 18/2
b = 9

9 = k + 10
9 - 10 = k
k = - 1

Please help! Israel added $80 to his savings. This added amount represents 1/8 of his total savings. If s represents the total s

Montano1993 [528]

Answer:

$s+80=\dfrac{1}{8}s$

Step-by-step explanation:

Let s represents the total Israel's savings.

Israel added $80 to his savings. Hence, he then had $(s+80).

This added amount represents $\frac{1}{8}$ of his total savings. $\frac{1}{8}$ of his total savings is

$\dfrac{1}{8}s$

Therefore,

$s+80=\dfrac{1}{8}s$
