Answer 1

$\huge{\frak{\underline{\color{pink}{Answer}}}}$

Given:

Find the probability of getting even composite number between 1 to 30.

Information:

There are 13 even composite numbers between 1 to 30.

Solution:

Probability = $\sf{\red{\frac{Favourable \: outcomes}{Total \: no. \: of \: outcomes}}}$

So, the probability is $\frac{13}{30}$.

Answer 2

Answer:

The sample space is,

n(A) =30

the event is getting even no.

B= { 2,4,6,8,10,12,14,16,18,20,22,24,26,28,30}

n(B) = 15

The probablity is

p(A) = n(B) ÷ n(A)

=15÷30

=2
