probability! Math
A number cube is rolled and the spinner is spun. Find each probability
1) P(6 and B) 2) P( odd number and E) 3) P(N>3 and A, B, or C) 4) P(n<3 and vowel) Spinner letters contain F,A,B,C,D,E :confused: Help!! |

How many sides has the cube and how many letters on the spinner?
Can we assume it is a 6-sided die and 26 letter spinner? |

The probability of any number on the cube is 1 in 6. The probability of a letter is 1 in 6. The spin and roll are independent events so the probability of a particular number and a particular letter (question 1) is simply the product of the two probabilities (1/6 * 1/6). For question 2, the letter E is 1/6. The odd number is 3/6. You can figure out the probability and you should be able to figure out the rest of the problems. |
