Answer 2

Given :

Two dice are thrown Simultaneously .

To Find :

• Both numbers are prime numbers .
• The sum of both number is less than 5 .
• First Number is less than second Number.

Solution :

i) Both Numbers are Prime Numbers .

$\sf\bigstar\:{Probability=\dfrac{Favourable\:Outcomes}{Total\:Outcomes}}$

= 9/36

= 1/4

ii) The Sum of both number is less than 5 .

$\sf\bigstar\:{Probability=\dfrac{Favourable\:Outcomes}{Total\:Outcomes}}$

= 6/36

= 1/6

iii) First Number is less than Second Number .

$\sf\bigstar\:{Probability=\dfrac{Favourable\:Outcomes}{Total\:Outcomes}}$

= 15/36
