Question

PLEASE LET ME KNOW IF I'M RIGHT:

A. 5*Math.random()                           integer   OR   real          smallest possible = 0.0       

largest possible =    4.999   

B. Math.floor(Math.random()+1)        integer   OR   real          smallest possible = 0          

largest possible = 1             

C. Math.ceil(3*Math.random())+10    integer   OR   real          smallest possible = 3          

largest possible =   10             

Answer 1

basics Math.random()  will generate number between 0 - 1

A. 5*Math.random()                        

result will be real number

smallest possible = 0.00000001 but not zero exactly

largest possible =    4.999   

B. Math.floor(Math.random()+1)        

integer

smallest possible = 1          

largest possible = 1     

always 1 the above code generate numbers 1.0 to 1.9 so .. math of floor number is 1

C. Math.ceil(3*Math.random())+10   

integer

smallest possible = 11

largest possible =   13
