    what the main problem says is a number cube is rolled and a spinner is spun

    and the problem is it say three or consonant

    so that means we have to do one sixth times something

    and a cube is rolled, the cube has six sides so thats where you get one sixth from

    haha no i mean like if you add the sum of what you spin and what you roll

    like the probability of a three and a constant?

    a constant is just a number. in this case, from what i assume from what you tell me, it would be just a number spun or rolled and you keep getting it. like roll the cube, get a 4. roll it again, get a 4. over and over...

    so thats all it is is a number being rolled on a dice over and over

    yeah or spun

    so if thats what the question is asking, then you just multiply probability 1/6 * 1/5

    these are letters though so we might say letters being spun over and over

    oh ok so for multiple times you have 1/6 * 1/5 and then you add the same probability for the roll for however many times

    like you want to roll a three a number every time for three times...the probability would be 1/6 * 1/5 + 1/6 * 1/5 + 1/6 * 1/5

    but we looked in the back of the book and the answer is one over ten

    1/6 x 3/5

    yeah that would be 1/10

  32. anonymous

    and then i have to simplify that

  33. anonymous
    • 5 years ago
    Best Response

    and im guessing that would turn that into 1/10

  34. anonymous

    yeah it would. its 1x3/(6x5) = 3/30 = 3/(3x10) = 1/10

    do you see how it happened? it was by factoring out the three from the denominator and numerator

    a factor of 6 means numbers that can multiply to get 6. if the numbers on the cube are 1, 2, 3, 4, 5, 6 then the factors are 1, 2, 3, and 6 so for the probability of a factor of six would be 4/6 or 2/3

  45. anonymous
    • 5 years ago

    and since they are a-e you want a d, the probability is 1/5 so multiply 2/3 * 1/5

    I Got a question how did you get 1/5

  48. anonymous
    • 5 years ago
    Best Response

    Medals 0

    because the spinner has five choices...its the same with the cube. you have six sides so the probability of getting say a 6 is 1/6 i.e. one out of six. since you spin and you have to land on one you have 1/5
