​

Answer 1

Answer:

2/5

Step-by-step explanation:

no. of prime numbers in first ten natural numbers=4 i.e., 2,3,5,7

probability= 4/10=2/5

Answer 2

Answer:

$\frac{2}{5}$

Step-by-step explanation:

$\text{Ten Natural Numbers are 1,2,3,4,5,6,7,8,9,10}$

$\sf \: Total = 10$

$\text{Prime no. are 2,3,5,7}$

$\sf \: Total = 4$

$\sf \: Probability = \frac{Prime no.}{total \: number }$

$\implies \: \cancel\frac{4}{10} = \frac{2}{5}$
