Basic Probability. I believe this is the first probability problem I'm doing on the blog. I've had a love/hate relationship with probability in the past. Like a lot of other things in life, repetition helped over the years.Let's not talk about Probability Theory. 😣 When I was learning it, my brain took a long while to grasp it. When that course was over, I breathed a sigh of relief. Some things really do take time. In the the case of my brain and probability theory, it was taking more time than the semester would allow. 😅
To solve this week's problem in completion, you need to recall the following math skills:
✔️ How to use basic probability formulas
Yeah, that's it. Here is WMP! #25:
Happy solving!

Well, once you get the correct formulas, you just need to make sure that you put the given values in the correct places in the formulas. (I can't tell you how many times I've seen that kind of mistake.) Here's how I worked out the questions:
Notice in part (iv), I gave an explanation why the events are independent, even though the question didn't ask, "why or why not?" It's not a coincidence that the answer from part (iv) is the same as the answer from part (i). When events are independent, one has no effect on the other. So, the probability of both events occurring is the same as multiplying their individual probabilities. Read more about independent events from MathisFun's page, Probability: Independent Events.
