Question

A die in which the numbers 1 to 6 are written on the faces is thrown. What is the probability of falling an even numbered face

Answer 1

Answer:

probability of getting even number= 3(2,4,6)

probability of getting an even number = 3/6

that is 1/2

Answer 2

Solution:

• We know that die contains numbers from 1 to 6.
• Out of this there are 3 even numbers namely 2, 4, 6.

Now, the probability of getting even number can be written as:

$\rm{Probability \: (even \: number)= \dfrac{Number \: of \: favourable \: outcomes}{Total \: number \: of \: outcomes} }$

Since there are 3 favourable outcomes out of 6,

$\Rightarrow \sf{P \: (even)= \dfrac{3}{6} }$

So,

$\Rightarrow \sf{Probability \: (even)= \dfrac{1}{2} }$

∴ Probability of getting an even number is ½

• Probability of a particular event happening plus the probability of the event not happening is always 1.
• Probability of any event lies between 0 and 1.
