Answer:
1.8 cycles
Step-by-step explanation:
The average number of clock cycles per instruction is given by the sum of the product of each possible number of cycles by its likelihood.
1 cycle: 50%
2 cycles : 25%
3 cycles : 20%
4 cycles : 5%

The average number of clock cycles per instruction is 1.8.
