There are 2 traffic lights. Bart knows the probability of stopping at the first light is 40%, stopping at the second light is 50% and the probability of stopping at no lights is 20%.
Apparently the chance is 10% and not 20% of stopping at boh lights. I thought they were independent but the opposite is true. So I used the formula for dependent probability. Now I'm trying to figure out how I can find P(B=R | A=R)
- What is the probability of stopping at both lights?
- What is the probability of stopping for at least one light?
