I think the answer is D. The other answers are unreasonable. Wyatt would not get the promotion and just because Tammy's lowest value is bigger than Wyatt's doesn't mean that Tammy gets the promotion. The only reasonable answer is D.

What is r if s=c(h+r)<br>

DerKrebs [107]

Answer:

Step-by-step explanation:

Divide both sides by c

s/c = c*(h + r)/c

s/c = h + r

Subtract h from both sides

s/c - h = h-h+r

s/c - h = r

When Ryan is serving at a restaurant, there is a 0. 75 probability that each party will order drinks with their meal. During one

Mnenie [13.5K]

Answer:

0.82

Step-by-step explanation:

We are given that

Total number of parties=n=6

The probability that each party will order drinks with their meal,q=0.75

The probability that party will not order drink with their meal=p=1-0.75=0.25

We have to find the probability that at least one party will not order drinks with their meal

Binomial probability distribution

$P(x=r)=nC_rq^{n-r}p^r$

Using the formula

$P(x=0)=6C_0(0.75)^6$

$P(x=0)=\frac{6!}{6!}(0.75)^6$

Using formula; $nC_r=\frac{n!}{r!(n-r)!}$

$P(x=0)=(0.75)^6$

$P(x\geq 1)=1-P(x=0)$

$P(x\geq 1)=1-(0.75)^6$

$P(x\geq 1)=0.82$

Hence, the probability that at least one party will not order drinks=0.82
