<h2>
The probability that Annie has selected the cards numbered 1, 2, and 3 is </h2>
Step-by-step explanation:
Here, the total number of cards in the set = 10
The cards are numbered as 1,2,3,4,5,...., 10
P(Any event E) =
P(picking a card with number 1) =
Now when the first card is picked, the number of cards left = 10 - 1 = 9
P(picking a card with number 2) =
Similarly, P(picking a card with number 3) =
So, the total probability that she has selected card with number 1, 2 and 3
=
Hence, the probability that she has selected the cards numbered 1, 2, and 3 is
