Ash, Kim and Josh meet every Wednesday to go for a run. If they all agree, they go for a long run rather than a short run. Based on previous experience, the probability that Ash is up for a long run is 0.4, Kim 0.3 and Josh 0.7.
What is the probability that they are all up for a long run the next time they meet. State any important assumptions that you make in order to calculate this probability.
Do I just need to multiply the three probabilities together? And what would important assumptions be?
Thanks
Yes, multiply
1. it is not blowing 60 knots and snowing
2. Josh does not change his mind because Kim decides yes.
3. They all show up
