For the first question
1/x-3, x cannot equal +3. As that would make the denominator 0.
For the second question.

A fair die is rolled nine times. What is the probability that
Lisa [10]

Answer:

The answer is 46/512 = 0.08984375

Step-by-step explanation:

In this question, success means to get an odd number on rolling a die.

The probability of success p = 3/6 = 1/2

So                                             p = 1/2

Now lets find probability of failure q

q = 1 - p = 1 - 1/2 = 1/2

So                                             q = 1/2

Let X  = x denotes the number of success in  n  trials.

So X  is a Binomial Random Variable

Which has the following parameters:

                                                n  = 9

as the fair die is rolled nine times and

                                                p = 1/2

Now the Probability of  x  success out of  n  trials P( X = x) is:

P(X = x) = p(x) =  nCx pˣ , qⁿ⁻ˣ , x= 0,1,2,...,9

P(X = x) = p(x) = nCx (1/2)⁹ = ₉Cₓ (1/2)⁹ = ₉Cₓ /512

Since the required probability is P (X < 3) So

P(X < 3) = P(X = 0) + P( X = 1) + P(X = 2)

             = 1 / 512 {₉C₀ + ₉C₁ + ₉C₂}                             nCr = n! / r! * (n - r)!

           

             = 1 / 512{ (9! / 0! * (9 - 0)!) + (9! / 1! * (9 - 1)!) + (9! / 2! * (9 - 2)!) }

             = 1 / 512 { 1 + 9 + 36 }

             = 46 / 512 =  0.08984375

So the required probability is 46/512

Four friends ordered a pizza cut into eight slices. The whole pizza was eaten, with each friend eating a different number of sli
raketka [301]

Answer:

{0,1,3,4}

Step-by-step explanation:

Given, total no of slices=8.

Total no of friends=4.

also each friend didnt ate more than the other three.

let a,b,c,d be no of slices ate by the friends 1,2,3,4 respectively.

given sum of a+b+c+d=8.

now applying the second condition

a\leq b+c+d \\b\leq c+d+a\\c\leq a+b+d\\d\leq a+b+c

so each of a,b,c,d must be less than or equal to 4.

which means 5 values are possible{0,1,2,3,4}.from this set you have to select 4 values such that their sum is 8.hence, those values are {0,1,3,4}.
