The probability of 3 bikes being red is .3*.3*.3=.027---The probability of a bike not being red is .7, so we have .027*.7=.0189. Since 3 bikes out of 4 can be chosen (4 choose 3) ways, we have 4 ways they can be arranged, which gives us 4*.0189=.0756, or 7.56% chance of 3 out of the next 4 bikes being red!!!!!!!!! \n" ); document.write( "
