Question

When a die is thrown, the probability of getting a number less than 7 is ____

Answer 1

We know that,

$\text{P(E)}=\frac{\text{n(E)}}{\text{n(S)}}$

where, P(E) is the probability of an event “E”

n(E) is the number of favorable outcomes and

n(S) is the total number of events in the sample space

Let, E be the event of getting a number less than $7$

Here, E$=\{1,2,3,4,5,6\}=$S

Thus, n(E)$=6$ and n(S)$=6$

$\therefore$ $\text{P(E)}=\frac{\text{n(E)}}{\text{n(S)}}=\frac{6}{6}=1$

Therefore the probability is $1$.
