Question

A number is selected at random from first ten natural
numbers. What is the probability of getting
a prime and
an even numbers
PLEASE TELL ME​

Answer 1

Answer:

sample space = ( 1,2,3,4,5,6,7,8,9,10) n(s) =10

prime numbers=2,3,5,7 n(a)=4

so probability of getting an prime number is 4/10=2/5

even numbers =(2,4,6,8,10) n(b)= 5

so the probability of getting an even number is 5/10=1/2

hope it helps

Answer 2

Answer:

total possible outcomes are 10,

no of possible outcomes are 2,which is only even and prime number.

so probability = 1/10.
