Question

There are 3 white counters and 1 black counter in a bag. If I take one at random, what’s the probability I have chosen a black counter?

Answer 1

black=1

white=3

total=4

P(black)=no of black/total

=1/4

Answer 2

Answer: 1/4

Step-by-step explanation:

Probability is an area of mathematics that deals with numerical representations of how probable an event is to occur or how likely a statement is to be true. The probability of an occurrence is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.

Where P(A) represents the probability of an occurrence "A" and n(A) represents the number of favourable outcomes. The total number of occurrences in the sample space is given by n(S). The probability of an occurrence is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty. The greater the likelihood of an occurrence, the more probable it will occur.

Given : 3 white counters and 1 black counter

To find : probability to choose a black counter

= probable outcomes/total outcomes

= 1/4
