Question

When a die is thrown list the outcomes of an event getting a) a prime no. b) a no. greater than 5​

Answer 1

a) getting a prime number

prime number from 1 => 6 = 2,3,5

probability = $\frac{3}{6} = \frac{1}{2}$

b)getting number greater than 5

number greater than 5 is 6

probability = $\frac{1}{6}$

hope it helps !!

Answer 2

Given :

• A die is thrown .

To Find :

• Probability of getting a prime number .
• Probability of getring a number which is greatef than 5 .

Solution :

$\longmapsto\tt{Total\:Outcomes=6}$

= 1 , 2 , 3 , 4 , 5 , 6 .

1. Probability of getting a prime number :

$\longmapsto\tt{Favourable\:Outcomes=3\:(2,3,5)}$

$\longmapsto\tt{Probability=\frac{No.\:of\:Fav.\:Outcomes}{Total\:No.\:of\:Outcomes}}$

$\longmapsto\tt{\cancel\dfrac{3}{6}}$

$\longmapsto\tt\bf{\dfrac{1}{2}}$

So , The Probability of getting a prime number is 1/2 ..

2. Probability of getting a number greater than 5 :

$\longmapsto\tt{Favourable\:Outcomes=1\:(6)}$

$\longmapsto\tt{Probability=\frac{No.\:of\:Fav.\:Outcomes}{Total\:No.\:of\:Outcomes}}$

$\longmapsto\tt\bf{\dfrac{1}{6}}$

So , The Probability of getting a number greater than 5 is 1/6 ..
