A committee of 9 members is voting on a proposal. Each member casts a yea or nay vote. On a random voting basis, what is the pro

dsp73

Answer:

The required probability is $P(x)=\frac{9}{128}$ or $P(x)=0.0703125$ .

Step-by-step explanation:

Consider the provided information.

A committee of 9 members is voting on a proposal. Each member casts a yea or nay vote. On a random voting basis,

The probability of yea or nay vote is equal, = $\frac{1}{2}$

So, we can say that $p=q=\frac{1}{2}$

Use the formula: $P(x)=\binom{n}{x}p^xq^{n-x}$

Where n is the total number of trials, x is the number of successes, p is the probability of getting a success and q is the probability of failure.

We want proposal wins by a vote of 7 to 2, that means the value of x is 7.

Substitute the respective values in the above formula.

$P(x)=\binom{9}{7}(\frac{1}{2})^7(\frac{1}{2})^{9-7}$

$P(x)=\frac{9!}{7!2!}(\frac{1}{2})^7(\frac{1}{2})^{2}$

$P(x)=\frac{8\times9}{2}\times(\frac{1}{2})^9$

$P(x)=\frac{4\times9}{2^9}$

$P(x)=\frac{9}{2^7}$

$P(x)=\frac{9}{128}$ or $P(x)=0.0703125$

Hence, the required probability is $P(x)=\frac{9}{128}$ or $P(x)=0.0703125$ .

How would I find the difference of 7/8 - 1/3 ?

Lemur [1.5K]

Answer:

$\frac{13}{24}$

Step-by-step explanation:

We have two fractions and are being asked to subtract them.

7/8 and 1/3 don't have the same denominator, so to do as so, we need to find the LCM of both denominators, multiply them to that, and do the same for the numerators.

So what is the LCM (Least Common Multiple) of 8 and 3?

24.

Therefore :

$\frac{7 * 3}{8 * 3} - \frac{1*8}{3*8}$

$\frac{21}{24} - \frac{8}{24}$

$\frac{13}{24}$

After 6 months, ammount left to pay = $1,840.34
On the seventh month, he payed of the debt with the interest (for one month).
Amount paid off at the seventh month = 1840.34(1 + 0.09/12) = 1840.34(1.0075) = 1854.14

Amount to have paid in the remaining 6 months = 314.83 x 6 = 1888.98
Amount saved = 1888.98 - 1854.14 = $34.84
