Three cards are drawn from a pack of cards randomly the probability all are of the same suit

Step-by-step explanation:

There are 26 red (13 hearts +13 diamonds) cards in a pack of 52 cards . Now, 3 cards out of total 52 cards can be selected in C (52, 3) = 52!/3! 49! =22100 no. of ways and 3 red cards out of 26 red cards can be selected in C (26, 3)= 26!/3! 23! =2600 no. of ways. Hence the required probability = 2600/22100 = 26/221 = 2/17.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
