How many different selections are possible? 1000 b. What is the probability of winning? Type an integer or a decimal) Enter your answer in the answer box and then click Check Answer

Explanation / Answer

a) Total number of different selections possible:

_ _ _

The 3 blanks represent the 3 digits drawn. Clearly we can select any of the 10 digits for each of the 3 banks. Therefore number of 3 digits sequences possible would be: = 10*10*10 = 1000

b)Now Probability of winning is 1 / Total number of possibilities because we win only if the exact sequence of the 3 digits matches. Therefore the required probability would be

= 1/1000 = 0.001

Therefore, 0.001 is the required probability here
