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 beca
olga nikolaevna [1]

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}}=\frac{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.
