A:
Answergiven,A bag consist of 29 tulip bulbsa) P(both bulb are red ) =      =[tex]P(first\ red\ bulb) \times P(second\ red\ bulb)[/tex]      = [tex]\dfrac{10}{29} \times \dfrac{9}{28})[/tex]      = 0.111 P(both bulb are red ) = 0.111b) P(first bulb is red and second yellow ) =      = [tex]P(first\ red\ bulb) \times P(second\ yellow\ bulb)[/tex]      = [tex]\dfrac{10}{29} \times \dfrac{12}{28})[/tex]      = 0.148   P(first bulb is red and second yellow ) = 0.148c) P(first bulb is yellow and second red ) =      =[tex]P(first\ yellow\ bulb) \times P(second\ red\ bulb)[/tex]      =[tex]\dfrac{12}{29} \times \dfrac{10}{28})[/tex]      =0.148 P(first bulb is yellow and second red ) = 0.148d) P(one bulb is red and the other​ yellow) =      = P(first bulb is yellow and second red ) + P(first bulb is red and second yellow )      = 0.148 + 0.148      = 0.296P(one bulb is red and the other​ yellow) = 0.296
