Algebra.Com's Answer #577743 by stanbon(75887) ![]() You can put this solution on YOUR website! The probability that a certain make of car will need repairs in the first six months is 0.27 . A dealer sells 5 such cars. What is the probability that at least one of them will require repairs in the first six months \n" ); document.write( "--- \n" ); document.write( "Binomial Problem with n = 5 ; p(need repair) = 0.27 ; p(not need) = 0.73 \n" ); document.write( "-------------------- \n" ); document.write( "Ans: P(1<= x <=5) = 1 - P(x=0) = 1 - 5C0(0.27)^0*0.73^5 = 0.73^5 = 0.7927\r \n" ); document.write( "\n" ); document.write( "========================================================= \n" ); document.write( " AND \n" ); document.write( "Luis has a coin that is weighted so that the probability that Heads appears when it is tossed is 0.52 . Suppose that the coin is tossed 4 times. What is the probability that all 4 tosses are Heads? \n" ); document.write( "P(x = 4) = 0.52^4 = 0.0731 \n" ); document.write( "-------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "---------------- \n" ); document.write( " |
