A number cube is rolled 63 times. predict how many times the cube will land on a number that is a factor of 6 .

Respuesta :

you said cube, so I assume a standard 6 sided die with numbers 1,2,3,4,5,6

how many times you said
we need to find how many fulfill the condition

how many numbers from 1,2,3,4,5,6 are a factor of 6?
1 is a factor
2 is a factor
3 is a factor
6 is a factor

so 4 numbers
there are 6 sides, so we would expect it to land of a factor of 6 a grand total of 4/6 or 2/3 times

so 2/3 of the time we will get a factor of 6

so find 2/3 of 63 to get number of times we get a factor of 6
2/3 of 63=2/3 times 63=42
so it will land about 42 times
