a. with a prime number written on it .
b. with a composite number written on it.
c. with a multiple of 6 written on it. ​

Answer 1

Answer:

a)n(s)=10

E:an event of drawing a sheet with a prime number written on it

n(e)=4

p(e)=4/10=2/5

b)n(s)=10

E:an event of drawing a sheet with a composite number written on it

n(e)=6

p(e)=6/10=3/5

c)n(s)=10

E:an event of drawing a sheet with a multiple of 6 written on it

n(e)=2

p(e)=2/10=1/5

hope my answer may help to you!
