Answer:
a) 5000 combinations
b) 200 combinations
c) 1000 combinations
Step-by-step explanation:
a) for the first cell there is 10 possibilities
for the second cell there is 10 possibilities
for the third cell there is 10 possibilities
for the last cell there is 5 possibilities
so the total number of possibilities= 10×10×10×5= 5000 combinations.
b) for the first cell there is 1 possibility
for the second cell there is 10 possibilities
for the third cell there is 10 possibilities
for the last cell there is 2 possibilities
so the total number of possibilities= 1×10×10×2= 200 combinations.
c) for the first cell there is 2 possibilities
for the second cell there is 10 possibilities
for the third cell there is 10 possibilities
for the last cell there is 5 possibilities
so the total number of possibilities= 2×10×10×5= 1000 combinations.
