Your friend, Jamie, rolled a number cube and got the number 5. On his next turn, he says he won’t be able to roll another 5 because he is only expected to roll a 5 once every six rolls. Is your friend correct? Explain your answer.

Answer:

Here's the sample =3=

Explanation:

Jamie is not correct. No matter how many times the cube is rolled, the probability of rolling a 5 will be 1/6.

Answer with explanation:

When a Number cube numbered from 1 to 6 is rolled once,

total possible outcome ={1,2,3,4,5,6}

Probability of each outcome that is ,


P(1)=P(2)=P(3)=P(4)=P(5)=P(6)=\frac{\text{total favorable outcome}}{\text{Total possible outcome}}=(1)/(6)

→So, each outcome has equal chance when a die is rolled 6 times.But in actual ,that is in experimental probability this seems impossible.

When you are dealing with theoretical probability,we state that ,yes when a number cube is rolled six times each outcome has equal chance of coming.

No, my friend is Incorrect,because here he is performing experiment in real life,there are chances that in next five trials ,number 5 only appears on the number cube,but when number of rolling of number cube becomes very high and higher, then probability of occurring of each number becomes same.
