Step-by-step explanation:

It is given that there are a total of 19 cards ({1,2,3,4, ...... ,19}).

Let S be the set of total cards.

S ={1,2,3,4, ...... ,19}

Total number of observations, n(S) = 19

Even number of cards is the set {2,4,6,8,10,12,14,16,18}

Total number of cards with even number on it = 9

Let E be the event of selecting a card with even number on it.

n(E) = 9

Probability of an event A can be formulated as:

In this case, formula of P(E) is:

The probability that the card chosen at random is an even number is:

step-by-step explanation:

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
