Question

a die is such that the no. 6 is twice as likely to occur as any other number. If such a die is rolled find the probability of getting an odd number.

Answer 1

3/6 is the probability

Answer 2

Answer:

The probabilities for 1 thru 5  must be equal and the total probability must be one so the individual probabilities must be:

1 -  1/7

2 - 1/7

3 - 1/7

4 - 1/7

5 - 1/7

6 - 2/7

The numbers 1, 3, and 5 are odd so the probability of getting an odd nmber

is 3/7   whereas the probability of an even number would b 4/7
