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

Translating a sentence into a multi-step equation
Kryger [21]

Answer:7x-4= 3

Step-by-step explanation:

4 less than the product of 7 and a number is equal to 3.

The answer is 7x-4= 3 beacuse:

(a.  whenever you have something less than , the first number in the sentence (in this cacse 4) goes after the second number (in this case 7) with a subtraction sign in the middle. (imagine this equation looking like 7-4 <u>for now)</u>.Thats a little trick i use whenever i have to write "something less than something"

(b. okay so now we know it has to be 7 times somethig -4=3, but now we just need to write the "product of 7 and a number" in proper form. in other words, whenever you get somethig times a number, it is always going to be  that number with an x right next to it. so thats why i made it 7x.

(c. "equals 3" is easy because you just turn it into an "=3".

(d. Now put it together. "4 less than the product of 7 and a number is equal to 3." becomes 7x-4=3.

Hope this helps :)) Also brainliest would be appreciated, worked pretty hard on this ! :D
