On an eight question true-false quiz, a student guesses each answer. What is the probability that he/she gets at least one of th
Fantom [35]

Answer:

P[at\ least\ 1] = 0.9961

Step-by-step explanation:

Given

Questions = 8

Quiz\ Type = True\ or\ False

Required

Probability that s/he gets at least one correctly

First, we calculate the probability of answering a question correctly

Since, there are just 2 choices (true or false), the probability is:

P(correct) = \frac{1}{2}

Similarly, the probability of answering a question, wrongly is:

P(wrong) = \frac{1}{2}

The following relationship exists, in probability:

P[at\ least\ 1] = 1 - P[none]

So, to calculate the required probability.

First, we calculate the probability that he answers none of the 8 questions correctly.

P[none] = p(wrong)^8

P[none] = (\frac{1}{2})^8

Substitute P[none] = (\frac{1}{2})^8 in P[at\ least\ 1] = 1 - P[none]

P[at\ least\ 1] = 1 - (\frac{1}{2})^8

P[at\ least\ 1] = 1 - \frac{1}{256}

Take LCM

P[at\ least\ 1] = \frac{256 - 1}{256}

P[at\ least\ 1] = \frac{255}{256}

P[at\ least\ 1] = 0.9961

<em></em>

<em>Hence, the probability that s/he gets at least one correctly is 0.9961</em>

the circular pool has a diameters of 30 ft. and a dept. of 70 ft. How much water I need to fill the pool
Andrews [41]
Volume of the pool will be defined as V = πr²h
V = π(15)²(70)
V = 15750π ≈ 49480 cubic feet of water..  or about 370, 136.1296 gallons

1 cubic ft is equal to 7.48052 gallons

Mark rolls 2 fair dice and adds the results from each. Work out the probability of getting a total of 5. Please help if you can!
Allisa [31]

Answer:

13.8%

Step-by-step explanation:

I have created a table that shows all of the possibilities that two die's can roll when summed up. If we count all of these possibilities we can see that there are a total of 36 outcomes. From all of these outcomes we can also see that only 4 outcomes sum up to be a total of 5. Therefore, we have to divide the number of times 5 is a possibility by the total number of outcomes to get the probability of actually getting a sum of 5.

5 / 36 = 0.138  ... multiply by 100 to get percentage

0.138 * 100 = 13.8%
