Question

Express, in terms of n, the probability that a probability of each counter is taken when a bag contains n counters, one is blue, and the rest are red.

A. 1/n
B. n/2
C. 1/(n+1)
D. 1/(n-1)

Answer 1

The probability of selecting a blue counter from a bag containing n counters, one blue and the rest red, is 1/n.

Step-by-step explanation:

To find the probability of selecting a blue counter from a bag containing n counters, one blue and the rest red, we need to determine the total number of counters in the bag and the number of blue counters. Let's say the bag contains n counters. One counter is blue and the rest are red. Therefore, the total number of blue counters is 1 and the total number of counters is n. The probability of selecting a blue counter can be expressed as:

P(B) = 1/n

Therefore, the answer is Option A: 1/n.
