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

A spherical tank has a capacity of 800 gallons. Using the fact that 1 gallon is about 0.1337 ft3, find the radius of the tank (t
nydimaria [60]

Solution-

Capacity of the spherical tank = 800 gallons.

1 gallon = 0.1337 ft³,

Volume of 800 gallons = 800 × 0.1337 = 106.96 ft³

Formula for the volume of sphere

V =\frac{4\pi r^{3}}{3}

Equating both the volumes

⇒ \frac{4\pi r^{3}}{3} = 106.96

⇒ r^{3} = 25.53

⇒ r = \sqrt[3]{25.53}

⇒ r = 2.94

∴ Radius of the sphere is 2.94 ft

Andy is wrong.
3/5 = 12/20
1/4 = 5/20
Add them up
12/20 + 5/20 = 17/20
17/20 is not equal to 4/9
