SUMMARY

This discussion focuses on calculating probabilities from two bags of straws. Bag A contains 1 white, 2 red, and 2 green straws, while Bag B has 2 white, 2 red, and 1 green straw. The probabilities calculated for drawing two straws of the same color and for drawing one red and one green straw are presented. The expressions for these probabilities are confirmed as correct but require evaluation for final answers.

PREREQUISITES
  • Basic understanding of probability theory
  • Familiarity with combinatorial counting methods
  • Knowledge of evaluating algebraic expressions
  • Experience with probability calculations involving multiple events
NEXT STEPS
  • Learn how to evaluate algebraic expressions in probability problems
  • Study conditional probability and its applications
  • Explore combinatorial probability techniques
  • Understand the concept of independent events in probability
USEFUL FOR

Students studying probability, educators teaching probability concepts, and anyone interested in solving combinatorial problems in statistics.

Summary:: Bag A contains 1 white straw, 2 red straws and 2 green straws. Bag B contains 2 white
straws, 2 red straws and 1 green straw. One straw is drawn at random from each bag. Find the
probabilities that
(a) the two straws drawn are of the same colour;
(b) one straw is red and the other one is green.

I don't know if my answers are correct.

My answers are:
a. 1/5*2/5+2/5*2/5+1/5*2/5

b. 2/5*1/5+2/5*2/5

Correct, but please post homework problems in our homework section (I moved the thread).
You should probably evaluate these expressions for final answers.
