Answer 1

Answer:

The required probability that all three cards are even is $\dfrac{3}{5}$  

Step-by-step explanation:

Given as :

The total number of cards = S = 5 cards

Or, n(s) = 1 , 2 , 3 , 4 , 5

Or, n(S) = 5

The number of cards to be chosen = E = 3 cards

Or, n(E) = 1 , 2, 3

or, n(E) = 3

Let The probability that all three cards are even = P (E)

So, According to question

The probability that all three cards are even = $\dfrac{number of event desire}{total number of events}$

I.e P (E) = $\dfrac{n(E)}{n(s)}$

or, P (E) = $\dfrac{3}{5}$

So, The required probability =  P (E) = $\dfrac{3}{5}$

Hence, The required probability that all three cards are even is $\dfrac{3}{5}$  Answer
