Ответ:
44.4%
Step-by-step explanation:
The probability in this case would be the specific number of pairs of means that we are asked to calculate, that is, blue divided by the total number of pairs, which would be the sum of the different colors, then:
We have that blue there are 4 pairs, and in total it would be 2 + 4 + 3 = 9, that is to say 9 pairs of means.
therefore the probability is:
4/9 = 0.444
Which means that there is a 44.4% chance of drawing a blue pair.
