Van guessed on all 8 questions of a multiple-choice quiz. Each question has 4 answer choices. What is the probability that he go

aleksandr82 [10.1K]

Answer:

0.267

Step-by-step explanation:

This can be solved using the binomial probability formula which is:

$P(success)=nCk*p^{k}(1-p)^{n-k}$

Where

n is total number of trials (here, the total number of questions is 8, so n = 8)

k is the number of attempts we are looking for (here, we want to find probability of 1 question correct, so k = 1)

p is the probability of success (here, success is getting a questions right. Since there are 4 choices and 1 is right, probability of right = 1/4)

Plugging all the info into the formula we get:

$P(success)=nCk*p^{k}(1-p)^{n-k}\\P(1QuestionRight)=8C1*(\frac{1}{4})^{1}(1-\frac{1}{4})^{8-1}\\P(1QuestionRight)=\frac{8!}{(8-1)!*1!}(\frac{1}{4})(\frac{3}{4})^7\\P(1QuestionRight)=\frac{8!}{7!*1!}(\frac{1}{4})(\frac{3}{4})^7\\P(1QuestionRight)=8(\frac{1}{4})(\frac{3}{4})^7\\=0.267$

Second choice is right.

Two spherical balloons are filled with water. The first balloon has a radius of 3 cm, and the second has a radius of 6 cm.

Sergeu [11.5K]

V=4/3*pi*r³;
Balloon A (3cm) has a volume of 113.1.
Balloon B (6cm) has a volume of 904.78.
Then you do 904.78-113.1, to get 791.68 cm³

In triangle RG shown below. m 63 and m 30 Which of the following is the 63

Tatiana [17]

Answer:

The value of the hypotenuse is 69.77 meters.

Step-by-step explanation:

To determine, in triangle RG, the value of its hypotenuse if its sides measure 63 meters and 30 meters, the following calculation must be performed, applying the Pythagorean theorem:

63 ^ 2 + 30 ^ 2 = X ^ 2

3969 + 900 = X ^ 2

√ 4869 = X

69.77 = X

Therefore, the value of the hypotenuse is 69.77 meters.
