Answer:

dependent and 1.26

Step-by-step explanation:

These two individual events are dependent on each other as first they draw it and then instant they eat two red candy pieces

Now the probability of the combined event is as follows

P(Probability of combined event)  is

= P(Event 1) \times P \frac{Event 2}{Event 1}

= \frac{55}{49} \times \frac{54}{48}

= 1.122 \times 1.125

= 1.26

We simply applied the above formula so that we can get the dependency or independency plus the probability of the combined event

Kryger [21]

Answer:

  • Price decrease in dollars = $4,148
  • Price of next model = $29,852

Step-by-step explanation:

The next car will be 12.2% cheaper. This amount in dollars is:

= Percentage decrease * Current model price

= 12.2% * 34,000

= $4,148

The price of the next model will therefore be:

= 34,000 - 4,148

= $29,852

zepelin [54]

Answer:

False

Step-by-step explanation:

If W and Z are vector spaces, then no, that is not necessarily true. That's not generally true for any circumstance unless the vector space W is a subspace of Z, or vice versa.

A construction company is considering submitting bids for contracts of three different projects. The company estimates that it h
julsineya [31]

Answer:

a.P(x)=\frac{n!}{x!(n-x)!}*p^{x}*(1-p)^{n-x}\\

b. E(x) = 0.3

c. S(x)=0.5196

d. E=5,000

Step-by-step explanation:

The probability that the company won x bids follows a binomial distribution because we have n identical and independent experiments with a probability p of success and (1-p) of fail.

So, the PMF of X is equal to:

P(x)=\frac{n!}{x!(n-x)!}*p^{x}*(1-p)^{n-x}\\

Where p is 0.1 and it is the chance of winning. Additionally, n is 3 and it is the number of bids. So the PMF of X is:

P(x)=\frac{3!}{x!(3-x)!}*0.1^{x}*(1-0.1)^{n-x}\\

For binomial distribution:

E(x)=np\\S(x)=\sqrt{np(1-p)}

Therefore, the company can expect to win 0.3 bids and it is calculated as:

E(x) = np = 3*0.1 = 0.3

Additionally, the standard deviation of the number of bids won is:

S(x)=\sqrt{np(1-p)}=\sqrt{3(0.1)(1-0.1)}=0.5196

Finally, the probability to won 1, 2 or 3 bids is equal to:

P(1)=\frac{3!}{1!(3-1)!}*0.1^{1}*(1-0.1)^{3-1}=0.243\\P(2)=\frac{3!}{2!(3-2)!}*0.1^{2}*(1-0.1)^{3-2}=0.027\\P(3)=\frac{3!}{3!(3-3)!}*0.1^{3}*(1-0.1)^{3-3}=0.001

So, the expected profit for the company is equal to:

E=-10,000+50,000(0.243)+100,000(0.027)+150,000(0.001)\\E=5,000

Because there is a probability of 0.243 to win one bid and it will produce 50,000 of income, there is a probability of 0.027 to win 2 bids and it will produce 100,000 of income and there is a probability of 0.001 to win 3 bids and it will produce 150,000 of income.
