Question

Find the probability of choosing an even number from the first 7 even natural numbers.

Answer 1

P(E) = $\dfrac{3}{7}$

Step-by-step explanation:

To find, the probability of choosing an even number from the first 7 even natural numbers = ?

All possible outcomes are:

1, 2, 3, 4, 5, 6 and 7

Total number of possible outcomes = 7

Let E be the event of getting a even natural numbers.

Favourable outcomes are:

2, 4 and 6

Number of favourable outcomes = 3

We know that,

P(E) = $\dfrac{Number of favorable outcomes}{Total number of possible outcomes}$

$=\dfrac{3}{7}$

∴ P(E) = $\dfrac{3}{7}$
