Phil has 7 green marbles and 3 purple marbles in a bag. he removes a marble at random, records the color, puts it back, and then

repeats this process until he has withdrawn 6 marbles. what is the probability that exactly three of the marbles that he removes are green? express your answer as a decimal rounded to the nearest thousandth.

The probability of selecting a green marble in one turn is 7/7+3 which is 7/10. For 3 turns, we will do\frac{7}{10} * \frac{7}{10} * \frac{7}{10} = \frac{343}{1000}

Let W be the subspace of R5 spanned by the vectors w1, w2, w3, w4, w5, where
Gwar [14]
To find W⊥, you can use the Gram-Schmidt process using the usual inner-product and the given 5 independent set of vectors. 

<span>Define projection of v on u as </span>
<span>p(u,v)=u*(u.v)/(u.u) </span>
<span>we need to proceed and determine u1...u5 as: </span>
<span>u1=w1 </span>
<span>u2=w2-p(u1,w2) </span>
<span>u3=w3-p(u1,w3)-p(u2,w3) </span>
<span>u4=w4-p(u1,w4)-p(u2,w4)-p(u3,w4) </span>
<span>u5=w5-p(u4,w5)-p(u2,w5)-p(u3,w5)-p(u4,w5) </span>

<span>so that u1...u5 will be the new basis of an orthogonal set of inner space. </span>

<span>However, the given set of vectors is not independent, since </span>
<span>w1+w2=w3, </span>
<span>therefore an orthogonal basis cannot be found. </span>

g Two teams compete in the NBA (National Basketball Associa- tion) championshipseries. The team who wins four games out of seven
Firlakuza [10]

Answer: The required probability is 0.32.

Step-by-step explanation:

Since we have given that

Probability of winning team A over B = 0.7

Probability of losing team A over B = 0.3

Number of matches = 7"

So, using the "Binomial distribution" :

We get that

P(X=5)=^7C_5(0.7)^5(0.3)^2=0.32

Hence, the required probability is 0.32.

Translate the difference of five squared and n into symbols.
stira [4]

Answer:

5² - n  

Step-by-step explanation:

Five squared  = 5²

                     n =        n     Subtract n from 5²

                 Diff. = 5² - n

We indicate "taking the difference" by a "minus" sign, so all the other options are <em>wrong. </em>
