Q7: Question 9. & 10. I need help

9 Suppose the time a child spends = waiting at for the bus as a school bus stop is exponentially distributed with mean 6 minutes. Determine the probability that the child must wait at least 7minutes on the bus on a given morning, 10. Suppose the time a child spends waiting at for the bus as a school bus stop is exponentially distributed with mean 4 minutes. Determine probability the child must wait between 3 as minutes on the bus on a given morning? 0. 1859
