Question

$the \: probability \: of \: gettng \: an \: even \: number \: when \: a \: fair \: dice \: is \: rolled \: once \: is$
​

Answer 1

Step-by-step explanation:

• Total favourable utcomes = 3 (2,4,6)
• Total possible outcomes = 6

• Probability = No. of favourable outcomes/Total possible outcomes.

• =) 3/6
• =) 1/2

Answer 2

Answer:

The sample space has 6 possible outcomes-

S={1,2,3,4,5,6}.

Let all outcomes are equally likely(fair dice).

Hence Probability of any one outcome occurring= 1/6.

The event that we get that an even number on tossing the die can occur in 3 possible ways.

Let E denote this event.

E={2,4,6}

Now P(E)=

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