Question

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

Answer 1

Answer:

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

Step-by-step 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:

$Probability = \frac{1}{4}$

So:

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

Recall that

$Probability = \frac{1}{4}$ --- for each ball

So, the equation becomes

$P(At\ least\ 2) = \frac{1}{4} + \frac{1}{4} + \frac{1}{4}$

$P(At\ least\ 2) = \frac{3}{4}$

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