The probability that a pink thimble will be drawn is 1/3
Probability is likelihood that an event will occur. The certainty that an event will occur is 1 which is equivalent to 100%.
This means that the value of a probability should not exceed 1 or 100% as percentage.
Probability = sample space / total outcome
The total outcome = 20 + 10 = 30 thimbles
the number of pink thimbles = 10
the probability of drawing pink thimble = 10/30
= 1/3
Therefore,the probability that a pink thimble will be drawn is 1/3
