cpi for first case $=2.2(1+2\times .2)$ as the stall required is $2$ and $2.2$ is the maximum stage delay. cpi for second state $=1\times (1+5\times .2)$ as now stall increase to $5$ as there are five stages before the address is calculated and the maximum stage delay now is $1.$ $\dfrac{\text{cpu_time1}}{\text{cpu_time2}}=\dfrac{3.08}{2}=1.54$

Probability that buckets other than $1$ are selected $= \dfrac{n-1}{n}$ This should happen $k$ times and each of the $k$ events are independent so $\dfrac{(n-1)^k}{n^k}$ When $k=1,$ probability of no collision $= \dfrac{n}{n}$ (for only one insert, there can ... $k>n+1$ probability of first collision $= 0$ (as it should have definitely happened in one of the previous $(n+1)$ insertions.
