He takes a counter at random from each bag.
The probability that he takes a red counter from the first bag is 0.3.
The probability that he takes a red counter from the second bag is 0.4.
What is the probability that he takes at least one red counter?
or multiply them? 0.3x0.4
Just need the clarification. Thanks.
Bag 1 has a propability of p = 0.3 for red counter. What is the complementary propability? it is q = 1-p.
Bag 2 has p = 0.4. Complememtary propability?
As there are two bags, the tree diagramm can be drawn as a two-tiered try.
How many possibilities exist in total? how many of them have one red counter or more? count them!
