mathefaro:lol. Modified* You are very correct. Abeg solve it. Two dice are thrown. What is the probability that the sum of the numbers is divisible by 3? Cc thankyoujesus, shyneptune. |
Re: Nairaland 2016 Jamb Tutorial Classroon [mathematics Thread] by thankyouJesus(m): 5:53pm On Feb 05, 2016 |
Geofavor:possible outcomes (1,2) (1,5) (2,1) (2,4) (3,3) (4,2) (5,1). Probability=7/36 |
Re: Nairaland 2016 Jamb Tutorial Classroon [mathematics Thread] by Geofavor(m): 6:06pm On Feb 05, 2016 |
thankyouJesus:(6,3), (3,6), (5,4), (4,5) (6,6) 12/36 = 1/3.... I just got it. Thanks for the eye opener. Btw, is there a quicker method? |

thankyouJesus:I don't understand o. I thought in a football game, we can have a total of three outcomes: win, draw, lose. :. The probability of a draw should be 1/3. But this isn't the answer |
Re: Nairaland 2016 Jamb Tutorial Classroon [mathematics Thread] by mathefaro(m): 8:10pm On Feb 05, 2016 |
Geofavor:The probability that the game ends in a draw = P(P draws the game) AND P(Q draws the game) My thoughts |
Re: Nairaland 2016 Jamb Tutorial Classroon [mathematics Thread] by Geofavor(m): 8:14pm On Feb 05, 2016 |
mathefaro: this would give us 1/3 x 1/3 = 1/9. The answer is. . . not 1/9 |

Re: Nairaland 2016 Jamb Tutorial Classroon [mathematics Thread] by thankyouJesus(m): 8:52pm On Feb 05, 2016 |

In how many ways can a delegation of 3 be chosen from 5 men and 3 women, if at least 1 man and 1 woman must be included? Thankyoujesus, mathefaro, shyneptune, umartins1 etc. Shouldn't this be 5C2 x 3C1 + 5C1 x 3C2 ? |
Re: Nairaland 2016 Jamb Tutorial Classroon [mathematics Thread] by Nobody: 4:08pm On Feb 08, 2016 |
