a) #P(R nn G) = 3/14 #
b) # P(B nn P) = 4/21 #

a) #P(R nn G) = 3/6 * 3/7 = 3/14 #

b) # P(B nn P) = 2/6 * 4/7 = 4/21#

#P(R,G) = 3/14#
#P(B, P) = 4/21#

First spinner: 3 Red, 2 Blue, 1 Yellow with a total of 6
#P(R) = 3/6; " "P(B) = 2/6; " "P(Y) = 1/6#

Second spinner: 4 Purple, 3 Green, with a total of 7
#P(P) = 4/7; " " P(G) = 3/7#

#a. P(R, G) = 3/6 * 3/7 = 9/42 = 3/14#

#b. P(B, P) = 2/6 * 4/7 = 8/42 = 4/21#
