Answer:
0.0791
Step-by-step explanation:
student forgets iClicker device with probability 1/4 each time she attends a class.
She sets out with her iClicker device to attend 5 different classes
A - forget device
A' - do not forget device
P(A) = 1/4
P(A') = 3/4
If she arrives home without her iClicker device (after attending 5 classes), what is the probability (to 3 SIGNIFICANT figures) that she left it in the 5th class?
So, she will not forget in 1st class AND not forget in 2nd class AND not forget in 3rd class AND not forget in 4th class AND will forget in 5th class, so:
1st 2nd 3rd 4th 5th
3/4 3/4 3/4 3/4 1/4 = 0.0791
