Answer:
P(she needs to wait for 3 more hours | She has already waited for 7 hours) = e⁻¹
P(she needs to wait for x more hours | She has already waited for 7 hours)
= e^(-x/3)
Step-by-step explanation:
P(she needs to wait for 3 more hours | She has already waited for 7 hours)
= P(she needs to wait for 3 more hours, She has already waited for 7 hours) / P(She has already waited for 7 hours)
= P(she needs to wait for 10 hours) / P(She has already waited for 7 hours)
= (1/3)exp(-10/3)/ (1/3)exp(-7/3) = exp(-1) = e⁻¹
P(she needs to wait for x more hours | She has already waited for 7 hours)
= P(she needs to wait for x more hours, She has already waited for 7 hours) / P(She has already waited for 7 hours)
= P(she needs to wait for 7+x hours) / P(She has already waited for 7 hours)
= (1/3)exp(-(7+x)/3)/ (1/3)exp(-7/3) = exp(-x/3) = e^(-x/3)
