Question

A. 0.50
B. 0.75
C. 0
D. 0.25

Answer 1

`P(At\ least\ 2) = 0.75`

Explanation:

Given

Balls = 1 to 4

Required

Determine the probability of selecting ball numbered at least 2

Here, we'll assume that all numbers have the same probability.

The probability of each ball will be:

`Probability = (1)/(4)`

So:

`P(At\ least\ 2) = P(2) + P(3) + P(4)`

Recall that

`Probability = (1)/(4)` --- for each ball

So, the equation becomes

`P(At\ least\ 2) = (1)/(4) + (1)/(4) + (1)/(4)`

`P(At\ least\ 2) = (3)/(4)`

`P(At\ least\ 2) = 0.75`
