Question

there are 7 balls numbered 1 through 7 placed in a bucket. what is the probability of reaching into the bucket and randomly drawing two balls numbered 7 and 3 without replacement. In that order? Express your answer as a fraction.

Answer 1

Given:

There are 7 balls numbered 1 through 7 placed in a bucket.

The probability is calculated as,

`P=\frac{Number\text{ of possible outcomes}}{\text{Total number of outcomes}}`

The probability of randomly drawing two balls numbered 7 and 3 without replacement.

The number of balls are 7.

`P=(1)/(7)*(1)/(6)=(1)/(42)`

Answer: probability is 1/42.
