Devin and Tej are playing cards. Devin draws a card, replaces it and then shuffles the pack. Tej then draws a card. Find the probability that:
a) both draw an ace
b) both draw the king of hearts
c) Devin draws a spade and Tej draws a queen
d) exactly one of the cards drawn is heart
e) both cards are red or both cards are black
f) the cards are different colours

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

(picture explains)

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.

step-by-step explanation:

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches

answer is 1
