What is experimental probability?

Theoretical probability describes how likely an event is to occur.

The theoretical probability of choosing a Queen is;

\rm Theoretical\ probability= (Observed \ frequency)/(Probability \ of \ selecting \ Queen)\n\n Theoretical\ probability= (16)/(4)\n\n Theoretical\ probability= (4)/(1)

What is experimental probability?

Experimental probability describes how frequently an event actually occurred in an experiment.

The experimental probability of choosing a Queen is;

\rm Experimental \ probability = Relative \ frequency\n\nExperimental \ probability = (4)/(15)

For comparing the theoretical and experimental probability of both equations.

\rm =(Experimental \ probability)/(Theoretical \ probability)\n\n= ((4)/(15))/((4)/(1))\n\n= (4)/(15)* (1)/(4)\n\n= (1)/(15)

Hence, the experimental probability is 1/15 less than the theoretical probability.

The first problem is true because with multiplication it doesn't matter which order it is in.

The second problem is false because you will get a different quotient depending on which numbers are on which side of the equation.

Soni has 196 pencils. If she puts equal amounts of pencils into eight boxes, she has four pencils left. How many pencils does she put in each box?

Answers

Soni can put 24 pencils can be put into each box with four pencils remaining.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

The best way to find this out is to find the total number, minus the remained.

In this case,

196 - 4 = 192.

As We have got to put the pencils into 8 boxes, we have to divide 192 by 8,

192 / 8 = 24.

Also, If x represents the number of pencils per box, the equation

8x + 4 = 196.

Therefore, Soni can put 24 pencils can be put into each box with four pencils remaining.

A coin is tossed 8 times. Which of the following represents the probability of the coin landing on heads all 8 times?

Answers

Answer:

\large\boxed{\large\boxed{Probability=1/256\approx 0.0039}}

Explanation:

Since, there are two possible outcomes for every toss (head or tail), the sample space for a coin tossed 8 times is 2×2×2×2×2×2×2×2 = 2⁸ = 256.

Landing on heads all 8 times is just one of the possible outcomes: HHHHHHHH ⇒ 1.

Hence, the probability is calculated from its own definition:

Probability = number of favorable outcomes / number of possible outcomes

  • Probability=1/256\approx 0.0039\text{ }\leftarrow answer

Answer:

1/256
